Q&A for How to Breed Freshwater Angelfish

Parent angelfish eat their fry primarily out of instinctual behavior and fear. Inexperienced angelfish, especially during their initial attempts at parenting, may mistakenly consume their eggs or fry due to various reasons, such as fear of infection or misinterpretation of other fish behavior. This behavior is common among many cichlids and serves as a survival mechanism, albeit unfortunate for the offspring. To avoid this, you can separate the eggs from the parents, but this is not always necessary. Sometimes, parent angelfish can really do a good job taking care of their fry on their own.

They usually pair up with someone their own size, but if there aren't any other fish, they might pair up.

No. You do.

They need more food than usual during breeding.

Yes, you can breed different strains of Angelfish.

You should not. It's not a great idea to keep any fish with the eggs. Every fish can be a predator for the fry or even just eat the eggs.

I've done that before, and the female did accept the new male. That is not always the case, but I would try it. If the female acts aggressive, separate the two as quickly as possible.

A 50 gallon tank could work, but it would be a little cramped. Bigger is always better and the bigger the tank, the less stress a fish would have. It is recommended to use a tank of 55 gallons or above for the greatest chance of breeding successfully.

The male has to fertilize the eggs; he will protect the eggs and fan them. After they have been fertilized, you can move the eggs, but they need a very low current over them, and they may still get fungus, which will kill the eggs. You can buy methylene blue to help prevent fungus.

If the glo fish are tiger barbs (have a triangular body and thick dark vertical stripes) then either the barbs or the angelfish have to be re-homed to a separate tank, as they are usually not compatible. If the glo fish are not tiger barbs, then most likely, the tank is too small to accommodate all of the fishes' territories, or there is not enough decor for stressed fish to hide in and/or divide territories.

Roughly about 100 every time but only a few of them survive to adulthood.

Move them as carefully as you can, or they may get sucked into the filter.

The other angelfish would probably eat them. I would put them in an other tank until they are ready to join the other angelfish.

Mine began breeding around three years of age, with their bodies about the size of the palm of your hand, and height around 10-12 inches from the tip of their top fin to the tip of the bottom fin.

Non-fertilized eggs will turn white. The parents may eat these eggs.

They usually start pairing off when small, when they're about 3 inches in height. But do note that they will not start laying or producing fry until they are a little more experienced, so you will have to be patient and feed them good quality food and they will start to produce fry for you which will definitely be worth the wait.

Sometimes, angelfish may still eat their eggs even after you make many accommodations. I do have a breeding pair that will do this regardless of what I do. I would recommend perhaps removing the eggs as soon as they hatch and hatching them artificially in a jar or something similar. But making sure that the temp is correct and whatever jar or tank you move the eggs to, remember to add a few drops of methylene blue and have a gentle flow in the container to stop fungi from growing.

As long as they are fertilized and free from fungi, then yes. To prevent this, make sure to add a few drops of methylene blue and have a slight current to the water to remove any chance of fungi growing.
