i found myself at a fish store the other day and was looking at fish tanks full of the same old same old clowns and damsels and blennys that they always have in stock when a court jester or rainford's goby caught my eye... so i asked the guy working there how much... he told me it was like $14 or something and i was feeling somewhat impuslive or perhaps even foolhardy so i told him to bag it up... now i got this fish in my tank and he wont seem to eat anything i stick in there now i know he would love to graze on some live rock and id be happy to let him but i have no live rock for him to graze upon... ive tried feeding him marine cuisine, tetramarine flakes, and emerald entree but he just isnt that eager to eat and looks skinny... so my question is ...what can i do to get my anorexic fish to eat? or is it that he wants to eat and the yellow tang in the tank is scaring him or w/e hes in the tank with a firefish yellow tang that are both quite small... also i have crushed coral instead of sand could it be he cant pick thru it well enough? sorry im being so long winded but id rather get a answer quickly...
