Feeding Methods and Technical Key Points for Juvenile Angelfish

Feed the fry opening food 5-8 hours after they leave the board and swim freely; feed them infusoria or brine shrimp nauplii. Feeding egg yolk water is no good; the fry do not like to eat it, and it fouls the water. Changing the water is unrealistic; you will find it simply cannot be done. The first feeding should be a small amount, just enough for every fish to get some. Feeding too much causes indigestion and instead kills the fish. After the first feeding, wait about 8 hours before the second feeding, so the fry have ample time to digest, adapt, and empty the "yolk water (milky mucus)" in their bellies. After that it is easy to manage; you just need to feed three times a day, with each feeding amount based on being finished within 1 hour.

For water changes for the fry, wait until the third day after feeding begins to do the first water change, keeping the water change volume at 10%-15%. First carefully siphon away the yolk water excreted by the fry, then add new water that has been aged and is at the same temperature. Add the water gently, slowly, and softly, and never let it hit the fry. After that, change the water once a day or once every two days.

From about the 7th day after feeding begins, you can feed small red worms; by about the 15th day, the fry have grown their dorsal fins, and at this point the fry can be fed red worms. You can move them into the rearing tank; using the drip-acclimation method, slowly lower the hatching bucket together with them into the rearing tank, then gently remove the hatching bucket. Then when the 30th day arrives, you can feed them any food you can provide, and water changes can also be done the same way as for adult fish. At this point, you can say your angelfish breeding has succeeded, and you can just watch this pack of "wolves" of yours grow by leaps and bounds day by day.
