Hello,\r\n\r\nI have an aiptasia problem that I cannot solve with Joes Juice alone as some of them are growing behind my live rock where I cannot reach them. \r\n\r\nI just got a Copperband butterfly from the LFS. I have had one before in this tank that did fine for years. The owner told me that the fish has been there for a month and has been eating. It was also pretty big. (3-1/2) inches. I placed the fish into a 75 gallon reef tank along with a yellow tang, a small mandarin dragon and a huge pacific sailfin tang. (4 1/2) inches long and when the sail is extended, looks like it is about 7 inches tall.\r\n\r\nThe butterfly is not eating and is on the top of the tank in the corner wagging his tail fin extremely fast. He's using up a lot of energy.\r\n\r\nI've tried frozen Mysis, frozen brine, and live brine shrimp by the way. He won't go near it.\r\n\r\nAlso, the sailfin tang is the big bully of the tank. I call him "Big Greedy" He has gotten the biggest because he is the most aggressive in the tank. I have witnessed him going over and worrying the copperband. The new fish is so scared it is almost jumping out of the tank when he comes near. The rest of the fish just slowly move out of his way.\r\n\r\nSo what should I be doing to keep this fish alive long enough to get used to the big sailfin and start eating? I don't think he will last but a few more days if I don't solve this.
