I am in the third week of cycling and have went through 4 damsels. HELP! What am I doing wrong??? The chemical readings are doing what they are supposed to do, but I keep losing fish. Everything has recently dropped chemical-wise so I added a cleaner shrimp yesterday to maybe help out the last damsel(domino) and when I got home guess who was dead. Yup. I have already fought one bout of ich and I think that's what got the last damsel...he was scratching the day before on the rocks in the tank. I now only have the one lonely shrimp and a blenny. I'm losing hope and beginning to think it was a bad idea to go salt water...I have a 40gal fish only(when they are alive that is) tank.
