I was well awesr of the concerns of how difficult this type of fish is to keep mainly because of their refusal to eat in a captive environment. When I went to my local fish store I made sure to see the fish eat before purchasing it to make sure that it was eating. I then brought it home and waited a day before feeding the fish I proceeded to feed it the next day and it sit only 3 bites of bloodworms. I repeated the feeding the next day. Same thing happened. I have since attempted a few more feeding a but it's now not eating anything. I assumed it was hungry as it always went to the surface when I did anything with the tank. I thought a varied diet was needed so I fed it some brine shrimp (frozen then thawed) it did not want to eat that either. I then went to the store and bought a few clans and tried freezing them and feeding that to it. It did not eat it either 2 min so I tied it to a piece of plastic and left it in the tank. Hoping its rock scavenging Nature would help it find the food and eat. Please help me. I am not new to this hobby and have been caring for some quite difficult fish. From scooter blennies (manderins) to seahorse small with great success. But today I fear I may lose my precious copper banded butterfly fish. I would appreciate any helpful feedback.
