I picked up a copperband butterfly fish 2 months ago to help with Aiptasia. It ate all the aiptasia within 2 days. I have never seen it eat since but seems healthy. I do see it picking at the sand and rocks throughout the day. Maybe it is eating Pods? Either way I have tried a lot of different foods with no luck. Pellets, mysis, brine, frozen food, and clams. It will not eat anything. This is my second clam and it will go right by it without eating. I end up pulling it out. Will it eventually start eating the clams?
