Fish eating fish food and then vomiting it out may be due to the following three reasons:

1. Gastrointestinal disease. It may be that there is a problem with the fish’s digestive system or gastrointestinal problems, which leads to this phenomenon.

2. The fish is not hungry. It may be that the fish is already full and not hungry yet.

3. Food problems may be caused by inappropriate food prepared by the owner, causing the fish to be unable to eat normally.

Tip:

When the owner finds that the fish has eaten fish food and then vomited it out, he can first observe the fish's belly to see if their belly is bulging. If the fish has eaten too much, the owner can stop feeding first and wait a few days for the fish to eat. Feed the food after the food in the baby's stomach has been digested.
