Not sure if they always do this, not saying that this always happens, but I picked up a yellow tang yesterday and by the evening he was eating green hair algae everywhere in my tank! of course this is great, because I've been waiting for my newly added CUC plus my cheato in my fuge to take care of it before adding corals, but this guy is chowing down like a cow. i actually saw a stand get 'slurped' into his mouth lol anyways, i had never heard of them doing this, but I wanted to get anyone's input on this. Of course this is nice for me, but is it okay for him to be eating it all? is this normal? thanks!
