Hi all...I'm new to all of this and I'm having a hard time keeping fish alive. Last night I lost my scooter blenny. When I took his body out of the tank and turned him over his belly had a gold sheen to it...could that be velvet? He was fine the day before. Also my yellow corgis wrasse got a crazy looking bacterial infection (I'm guessing)on his mouth and fin. Now he stays under the sand and I never see him. I got a yellow tang...died.yellow eye tang...died. Both had little white spots on their fins but it wasn't hardly any spots there. Now I have two clownfish left and I'm afraid they are next to go. Please help! I'm installing a UV sterilizer today hoping it will help. I have lots of coral so traditional treatments won't work I guess. Any advice would be greatly appreciated!
