Okay guys, my tank has been up and running for around 6 months now and for some reason the only thing I'm able to keep alive in this tank is coral's and damsels (and I hate damsels!). I had a diamond watchman goby which seemed to be doing fine until the damsels got to it and destroyed it. I've had 4 clowns, 2 each at different times and they barely made it a week. All my parameters are perfect and all my coral's have been thriving, growing and splitting like crazy! My CUC is solid and I've had a red star and yellow sea cucumber for around a month with no health issues. Could the place i'm getting the fish be bad? I've gotten them all at the same place and the last two clowns I got were at the store for a week and eating fine so the guy told me. I talked to a different store owner and he said it was strange that my coral's are thriving but I can't keep any clownfish alive in my tank...if anyone has any opinions or advice it would be much appreciated. Right now I have NO fish in my tank because I'm tired of wasting money on them. Thank you guys for everything!
