Ok so I got this 2 spot tang in a 60 cube. I want him gone. He has effectively killed a gramma in under a day and will not accept ANYTHING into this tank. He was the LAST fish in and has claimed this tank as his. What can i do aside from tear the whole thing down?? I dont care if he lives or not (i hate to be cruel but he's a pest) he doesnt harrass the cromis', clown, wrasse, anything thats been in there before him, but nothing new can come in. HELP! Any suggestions would be welcome, thanks!!!
