Q&A for How to Breed Angelfish

Yes - if not when they are eggs, definitely once they become free swimming. Get a separate tank for them, or a divider.

Yes, they might eat their eggs if they are stressed or feel threatened. There are also times when first time parents eats their eggs. They'll learn how to breed properly over time.

If you are selling them to a person, a 4-5 centimeter body is the best size. If you're selling them to a pet store, ask them what size they prefer.

No, it is not necessary, but it is highly recommended so the parents do not eat their fry. It is typical that they will eat their eggs the first couple of spawns, but after that, they will usually raise them by themselves.

You do not need to; however, if you'd like to raise them without the parents, you may. Angelfish are naturally great parents, so leaving them alone with the fry is my suggestion.

80-82 degrees is best, they hatch quicker in warmer temperatures (but do not go over 82 degrees).

You have to separate the fry into a smaller tank and feed them baby food till they get of right size.

If the eggs are bad they turn white, while if they are good they will stay a brownish-gray color. If you got a good pair they will remove the white eggs, if not a turkey baster will do the job.

Yes, it's best to maintain a regular night/day schedule for the fish, especially when caring for young.

Angelfish shouldn't swell up. No fish should. If you have a fish swelling up and floating (not dead, but seems to not be able to get down), it may have swim bladder disease.

Temperature might be affecting them, or you might be feeding them wrong. Try the foods and temperatures recommended in the article.

Angelfish can spawn almost every 7 days if the eggs are removed and raised artificially.

That's his job, plus if you have other fish in the tank they will eat them. It's best to have them in their own tank or put a divider in.

You may lose the eggs to the other fish or the parents may eat them due to the stress of danger. Fish will usually treat fish eggs as food. During spawning, angelfish may also be incredibly territorial and aggressive to other fish.

You can control the temperature of a tank with a heater or a chiller that you can usually buy at the pet store.

6 - 7 months old is a normal age for adulthood on angelfish, size really doesn't come into it.

Some angelfish take care of the eggs themselves and watch over their eggs to protect from fungus while some may lay their eggs in a high water flow area. Water flow helps limit the ability of fungus to settle on the eggs. Fungus is more common in water with higher pH. If you lower your pH, fungus is less likely to attack so strongly. Some aquarium chemicals made to lower pH can help in this case and can help control fungus.

You can feed them BBS (baby brine shrimp) or microworms. Over feeding BBS can cause swim bladder disease in some species.

If an angelfish's eggs are white within 24 hours, that usually means they are unfertilized. The parents will usually remove those eggs.

Right away after the male has stopped following the female over the eggs to fertilize.

Yes. My breeding pair spawned thrice in the community planted tank. Unfortunately, the babies were eaten, so it is better to keep the pair in their own tank.

You should not use any kind of gravel in the breeding tank.

They have fungus or bacteria. You can put antifungals and antibacterials in the water.

Female angelfish can lay eggs without a male, but they will not hatch without a male present to fertilize them.

Yes, it is, but be careful as the fry might eat the second batch of eggs. Move the second batch to a smaller nursery tank.

It does not matter. If you isolate one from the other, they will not be able to fertilize the eggs due to external fertilization and no breeding.

Newly-hatched fry will only need a 1-gallon tank as they will still be attached to their egg sack, but after they become free-moving (after about 4 - 6 days) they will need at least 10 gallons for an average-sized clutch, 20 gallons for ultimate growth. The tank should be a little bigger if you wish to raise the fry with the parents.

They will typically need to be 2" to 2 1/5". Angelfish that are average size and more mature will be more prone to breeding.

In great care and conditions, angelfish could be able to breed within seven months of age. With poor care, it could take much longer or may not happen at all.

No, a good day-night cycle is always a good idea in a fish tank, even when the fish are spawning.
