How big should my baby zebrafish be before I begin feeding brine shrimp to them?
If a brine shrimp can’t fit down the baby fish’s throat they won’t be able to eat it. What we usually do is to continue to feed the baby fish paramecia in addition to the live brine shrimp at least for a while. One way you can tell if the baby fish are eating the brine shrimp is that their bellies will turn red from the brine shrimp in their stomachs. Ideally, you should not feed more brine shrimp than the fish can eat in a short period of time… maybe a half hour. Several very small feedings would be preferable to a few large ones.
