Alright, new problem. Got my fish two days ago. Was a little hesitant on the diamond goby as it had what looked like poop stuck in his butt but it had white with it. I think I remember reading something about the white being a "trail of death", but couldn't remember and it had some brown in it too. The kid at the lfs
gave a smart *** response of "its taking a crap". And laughed me off. I was assurred it was nothing. My goby died over night. everybody else in the tank is loving life. Clowns happy and eating. Shrimp eating and wandering nicely. The goby was found dead being eaten by a nassarius and a hermit. So did I buy a bad fish or is my tank screwed up? Will the goby disease be contagious if it was a disease? My nitrates are a bit elevated 10-20. Did 20% PWC
on Friday. Will do another today after checking nitrates again. All other parameters seem good. NH4 0, NO3
0, N04 10-20, salinity 1.025, pH 8.0-8.2.
Anything else to worry about? I only use RO
