Okay so here’s the deal I have a 55 gallon salt water tank. It has been setup and running for well over a month. Just a few days ago I purchased 3 yellow tailed blue damsels. Well the very next day one of the fish was lifeless at the bottom of the tank and the other two just swimming away. Checked all the levels and everything seemed normal. The very next day another one dead. The other fish acting normal and healthy. It’s been a few days since and now the once happy fish is now hiding. What could possibly be wrong? I though damsels were soposta be hardy? I’ve come to the conclusion that my one damsel is a murderer. But what could be wrong with him?
I feed him a mixture of live and frozen brine shrimp. And now he’s hiding.
I don’t have live rock, is it a agood idea to get a few pieces even though I already have a fish?
