Thanks for the comments everyone.. I do try not to overfeed but right now all of my fish are being "acclimated" to a turkey baster for feeding so I don't have to waste so much in the process of trying to get them to eat.. I have one fish that will eat right from it now, but the clowns are nothing more than really small chickens.. 
Has anyone had/heard of detrimental side effects from using things like Phosban?
