Thats awesome..most die as they refuse substitute foods. If hes eating youve more than won 1/2 the battle! IME if they dont eat preped foods you need a mature reef with a deep sand bed or a good amount of life laden LR to sustain them. You should be fine if hes eating brine, once established they are very hardy. Also, males seem to be hardier from my exp....males have a longer pointed first dorsal ray (the fist fin on thier back is considerably onlger than those that follow) abd just seem to live longer in general.goodnews said:He is eating live brine. and if I take him back he'll die at the petstore... I'm ganna try my best.
