Alright guys! I need ideas. Velvet struck a week ago. I lost about 18 fish. But i still have 2 convict tangs and a 6line wrasse that i cant catch for the life of me. Pulling rock is not an option. Its in a 470g and all the rock and coral is cemented/glued in place. Fish trap hasnt been successful. Lights out-fish are out of sight in the rocks. Any ideas because i need to get these fish out asap!
