The lights just came on and I was totally heart broken. I lost both my clowns and my manderin goby. Something went on a rampage last night. I checked my water parameters and everything is in check. So either I have a voltage leak or my Domino damsel is a serial killer. He is hiding today though. My coral beauty is in hiding as well and he has what looks like fin rot. My rescued yellow tang and green chromis look fine. Anyone know how to check for voltage leaks into the tank water? It can't be much voltage leaking because I'm not getting shocked putting my hand in the tank. ARG!
