I have a 60 gal. I have about 40lbs of live rock. 2 clownfish, 1 yellow tang, 1 coral beauty, 1 valentini puffer, 1 yellow tail damsel, and 3 green chromis. I recently have lost a sailfin tang a clownfish my anenome, cleaner shrimp and a dottyback, and 2 of my chromis have died. I have tested everything and cannot find a problem. Anybody have ideas?
