guppy fish breeding

Since guppy fish are live bearers these are relatively easy for breeding as compared to egg layers fishes. For breeding you will need a healthy pair of guppy fish. If you are using one male per female then there may be chances that male will stress out females for breeding attempt. So in this case provide lots of hiding places for female in aquarium. Or you can put 3 females per male. Then in second case you may get 3 pregnant guppies. When males and females are present together then breeding will take place in most cases. Sometimes it is observed that female guppy fish are already pregnant when you buy them from fish tank shop. You can tell it by looking at belly if you find dark spot known as gravid spot then female guppy fish is already pregnant.

The aquarium should be 10 gallons or more.Set the temperature to 77 to 79 degrees Fahrenheit. Provide them protein rich food, live food will be the best choice but other will also do fairly well. Change the 25 % of water per week to encourage breeding. The gestation period of female guppy fish is about one month then she will release 10-40 babies in 1-2 hrs.The female are capable of giving birth for many months even in absence of males. When female is about to give birth then her belly will become thick and you can see gravid spot. Also you can notice some change in behaviour that is she may eat less food or move slowly.

If you are having only one main fish tank.

If you are having only one main fish tank. Then there may be high chances that the new born babies will get eaten by the mother or other fishes. However mother guppy fish is not interested in eating till she give birth to all babies it may take about 1 hour. So you have further choices.

If you are having fairly large aquarium then you can provide lots of hiding places by adding fake or live plants. You can add java moss or java fern. Add floating type aquarium plants and remember the other fish should not be able to see or access the babies. Remove the gravels before hand because fry of guppy fish may die if gravels fall on them. You can use spawning mop to provide hide out and caves made up of rock and marble chips.

If you want to go for another option there is 2 other equipment available in market known as breeding box and breeding net. Breeding box is plastic chamber in which you can put the pregnant female. While she give birth the babies enter to another chamber present at the bottom of it through the holes while mother guppy fish can not. Here you have to put the female while she is giving the birth or before hand. Here you need not to be present at the time of birth.

The other option is breeding net. It is box made up of net and it can be attached to the Wall of aquarium. You can put the females in it but you need to be present because here babies will be present with the mother. When she complete giving birth then move her to main tank. The breeding net will provide protection from adult fishes in same aquarium. The breeding net should be present where proper temperature and water circulation is maintained.

If you are having separate fish tank.

Then put the breeding pair in separate aquarium. When female give birth to babies after that remove back the female to main aquarium. The size of this separate aquarium must be 5 gallon or more. Remember not to add gravels and use fish tank sponge filter. If you are using any other powerful aquarium pump then they may get sucked up in fish tank pump or fish tank filter. So decrease their power or tight their ends. So they may not get sucked up. If you have moved the guppy fry from main aquarium then add water of main aquarium and try to maintain same parameter as of main tank. Do 25% water changes per 3-4 day.

Feeding and Care of Fry:

Feed the fry brine shrimps, newly hatched daphnia or you can give them hard boiled egg's yolk the yellow portion of egg. Form a thick paste of egg yolk then add very tiny amount of it.Try not to add it in extra amount, if possible remove the remaining food from aquarium other wise it may spoil. But doing so don't harm the babies. You cab also crush the flake food then form a paste then give to guppy fry. Give them 4-5 times in a day but in very small amount. As i have told you earlier cover any suction device if present. Switch on the light for 14 to 16 hours only. Set the temperature to 80 degrees Fahrenheit.

Tip of the day:
 Many of the fishes are victim of stress. Due to stress many fatal diseases like itch can outbreak. People are in habit of keeping their fish tank free from plants, caves or rocks.

To find difference between male and female guppy fish you have to note following things. Male guppy fish are more colorful as compared to female and male have larger fins as compared to female. The most easy way to tell the difference is by looking to their anal fin. The males have more pointed and developed anal fin know as gonapodium which is used to pass sperms to females. Females have broader anal fin which look like fan. Female guppies are larger and much rounder then males. The above one is male guppy while below one is female. You can easily see eyes of babies inside the female's body. By the given images you can easily note the differences among guppies.

Tip of the day

Many aquarium fishes are victims of over feeding rather then under feeding. People are not aware of the quantity which are needed by their fishes. Fishes are over dependent on their instinct. They do not realizes when to stop. Due to overfeeding they may suffer from serious problems like bloat, pot belly etc. You should feed only 2-3 minutes of food. If food is still left after 3 minutes then you are overfeeding. Also the left food is one of the main reason for polluting your fish tank.

guppy fish care

The guppy fish are one of the favorite aquarium fishes. These are small in size with vibrant colors. Males are generally more colorful and smaller in size as compared to female.

They are very cheap but some types may be expensive. Guppy fish are live bearers which means they directly give birth to babies just like molly fish. They require less water as compared to other fish and care is easy. You can put 1 inch of guppy fish in per gallon of water. Guppy fish can eat wide range of food live as well as frozen. You can give them brine shrimps, tropical flakes, floating type food, blood worms. Give them 2-3 times per day. Don't over feed them it may be harmful for you guppies. If food is still present for 3 minutes that means that you are overfeeding them. Guppy fish are peaceful by nature but sometime may become territorial. Put them in a group of 5 or more.

They like brackish water in tank so put 1 teaspoon of aquarium salt per gallon of water. They can survive in wide range of temperature 23 degrees to 30 degrees Celsius. Provide them lots of hiding places and live plants to decrease stress on them in the form of fish tank decorations. Try to put 2 -3 females per male because male may chase female for breeding and females will get exhausted and may die. Change about 25 % of water once in a week. Do not mix any large fish other wise guppy will serve as food for them. Also don't put them with any fin nipping fish.

difference between male and female angelfish

This is quite confusing to tell difference between male and female angelfish. You can get idea by looking at their body feature but this is not 100 percent valid until you wait for spawning time.

Generally it is observed that male angelfish have more rounded crown or area right above their eyes. Males grow faster as compared to females. Males have more fatty and robust body ascompared to female. Females have straighter line of their dorsal , or top fin , to their eyes. By observing their behaviour you can again get some idea of difference. Males show their papilla when the females are around.

Papilla : This is pencil point size pink organ which is located between ventral and anal fin of angelfish. Above picture is having both male and female.This is generally observed near the spawning period. The female will show bulge in this area when she is gravid that is carrying eggs. While the females papilla is more blunt and wider. During spawning females lays eggs on tilted flat surface and then males will touch the eggs with its papilla.

Note: If no males are present then 2 females may spawn together. So look for the size of papilla. If this happens then soon eggs will turn white. You can see the picture for more difference.

dalmation molly fish breeding

You must be knowing that all molly fishes are same species so you can breed any one of them with any other Molly fish. Breeding is very simple task. You need one male dalmation molly and few females with good water conditions. The number of females should be more then the males because males like to chase female dalmation molly, this makes females more stressed. She can even give birth to several batches of babies over a year even in absence of males because of their sperm holding capacity. Before hand you should also arrange home for new babies else avoid their breeding. If female dalmation are stressed then they may give birth to unhealthy babies or immature babies. So try to put lots of hiding places for females.

The gestation period of females is of about 30 -40 days. Females will start becoming more rounder as the time pass. When the female will about to give birth her stomach shape will be like \___/. Then females will give birth directly to fries. Remember they are live bearers. Dalmation molly will give birth about 30-40 fries at a time in time of about 1-2 hrs. In my case they give to birth to 30 babies in 1 go and on the next day she again give birth to 10 babies.

Remember to shift the mother or any other fish away from babies in separate fish tank otherwise dalmation molly will eat the babies. However mother dalmation will not react to babies while she is delivering the babies but after process is complete then she may try to eat them.

You can use breeding nest if you are not having any separate fish tank for babies development. Breeding nest is made of separate net fitted on plastic structure and you can attach it in main fish tank. You can also go for breeding box which have separate chamber for fish on the top from fish fries may pass to bottom chamber where no other adult fish can access. You can put babies in it till they grow enough that is about for 1 month.In these you should have proper water circulation and steady temperature.

If you are putting them in separate fish tank then remove gravels from the tank else fries will be crushed under them and use sponge filter so fry may no got suck in any other filter. Feed the babies crushed flake food and try to avoid disturbance to them. Then 25 % of water in a week.Don't over feed them. If you are having live plants in tank of babies it will benefit them.

Difference between male and female dalmation molly

It is very easy to distinguish between male and female dalmation molly. Female bodies are more round while the male are slender in shape. The most common and easy method to distinguish is that female have fan shape anal fin while the male have more developed fin known as gonapodium. Which is used to pass sperms in female body. Also males are more aggressive and like to chase females. So it important that number of females should be more as compared to males and their should be lots of hiding places in fish tank. The above one is male and below one is female. Look at the anal fin to distinguish them. The male's have thin stick shape fin while female's fin is broad and fan shape. These body features can be easily observed in other mollies and many live bearers species.

Dalmation molly are live bearers which means they does not lay eggs, they directly give birth to young fry. They can do well in small aquariums. Molly tends to eat their babies just after giving birth so you need to separate the babies from their mother as well as other tank mates. Sometime they try to chase other tank mates with larger fin. To avoid stress put 1 male with 2-3 female. So you require lots of hiding places or breeding net or breeding box will serve the need.

can i add table salt in aquarium

Common table salt which we use in our food is NaCl with some amount of iodine and other useful additives. Many of us had fishes who got suffer with some parasites infections like itch and salt treatment method is extremely help full to treat fishes with itch infections.

But as i have already told that table salt contains iodine and many people believes that iodine is extremely dangerous to aquarium fishes but on the other hand many people also believe that it is harmless. Actually there is controversy over this. So it is recommended to use kosher salt if you don't want to take risk. However i would like to share my personal experience with you all people.

My personal experience :

I was having 2 rosy barb and few black skirt tetras. Everything was working fine then i decided to brought 2 more tetras to the same aquarium. I went to aquarium dealer and bought 2 more. Without noticing them i added them to main tank and what i found they were having white spots all over their body and in next few days i found that each and every fish are having white spot and those poor fishes were rubbing with each other and also with filters trying to get some relief. Then i went through google and decided to add iodized table salt because it was present in the kitchen. I couldn't resist my self. I added table salt, i added 1 spoon per gallon and raised aquarium temperature to 32 degree Celsius. But everything was fine and after 4-5 days i found that itch had been disappeared and every fish is living fine till now. So finally i would suggest that you can add it at your own risk or may be i am lucky.

Molly Fish: The Tiny Tank Rockstars Every Beginner Needs

Imagine this: You’re a newbie aquarist, staring at an empty tank, dreaming of a colorful underwater world. Enter Molly fish—these little tropical champs are about to turn your tank into a lively party! They’re easy to care for, gorgeous to look at, and—warning!—they breed like there’s no tomorrow. Ready to meet your new aquatic BFFs? Let’s dive in!

Why Mollies Are the Cool Kids of Aquariums

Molly fish (Poecilia sphenops, if you’re feeling fancy) are the perfect starter fish. They’re chill, hardy, and don’t throw tantrums if you mess up a little. Oh, and they’re livebearers—yep, no eggs, just tiny babies popping out like popcorn. But here’s the catch: one day you’re admiring three mollies, and the next, you’re a fish grandparent to 50 fry. True story!

Setting Up Their VIP Tank

• Size: Start with a 10-gallon tank. But if they start a baby boom (spoiler: they will), upgrade to 20 gallons or risk a fishy traffic jam.
• Temperature: Keep it cozy at 72-82°F (22-28°C)—think tropical vacation vibes. A heater is your best bud here.
• Water Tricks: Slightly brackish water (a teaspoon of aquarium salt per gallon) makes them extra happy. Add a good air pump or filter for that crisp, clean flow they love.
• Feeding Time: What’s on the Menu?

• Mollies are foodies with no fuss. They’re omnivores, so mix it up:

  • Flake Food: Their daily bread—grab high-quality stuff.
  • Live Treats: Brine shrimp or bloodworms? They’ll do a happy dance.
  • Veggie Vibes: Toss in some blanched spinach—they’re not picky!

  Pro tip: Feed small amounts twice a day. Overfeeding? That’s a recipe for a cloudy tank disaster.

  Breeding Mollies: Babies, Babies Everywhere!

  Want to play fish matchmaker? Mollies are your wingmen. They’re breeding machines—females can drop 20-100 fry every 30-40 days. And get this: they store sperm like champs, so even without a male around, surprise babies are coming! Pet store mollies? Often pregnant before you even say “hello.”

How to Spark the Magic

• Load them up with protein-rich snacks (live food works wonders).
• Keep the tank peaceful with plants or a breeding box—those fry need a safe hideout, or mom might turn into a snack monster.
• Watch the chaos unfold as your tank becomes a fry daycare!

Fry Survival 101

Newborn mollies are tiny but tough. Crush some flakes or grab fry food, and give them space. Too many? Time to rehome or flex your fish-whisperer skills at the local shop.

The Molly Personality: Peace, Love, and Tank Life

Mollies are the zen masters of the fish world—peaceful, social, and drama-free. They vibe with guppies or tetras but steer clear of tank bullies like cichlids. Keep them in groups of 3+; solo mollies get lonely (and who wants a sad fish?).

Quick Stats to Impress Your Friends

• Lifespan: 3-5 years—longer if you’re a tank rockstar.
• Size: 2-3 inches of pure cuteness.
• Varieties: Black Molly, Dalmatian, Sailfin—pick your fave!
