I bought needlefish a while back. At the store he only ate feeders. I attempted to starve him. I waited three days and he ate nothing so I gave him feeders. After he was well adjusted I tried again and its like he doesnt even notice the pellets floating there. Then I tried some frozen brine shrimp. Waited 3 days without feeders, put the frozen brine shrimp in, not only did he ignore it but actually swam away from it. Now I haven’t put feeders in for a day and the last time I did I dont think he got any so it’s probably been about 3 or 4 days but I know for sure atleast a day. I put some frozen krill into the tank with no results again. He just let it go right by him. Any suggestions how to get him to eat frozen food?
