i was told this might be a saltwater goby, but i purchased it as a brackish goby. he seems to be doing well in my tank, but if he's saltwater, i'd rather find him a better home than my brackish tank. thanks.
i would, but the lfs i picked it up at kept it in a brackish tank. perhaps i could take it to a different store and get some credit or something. or at least know that he's not going to die of kidney failure.
