I'll start out by admitting that I did a stupid thing. I went to Petco (I know) because I was told they had batfish and I wanted to see one in person. There were no batfish, but there was this really pathetic looking Mandarin Dragonette that the fish-keeper guy thought a tennis ball sized piece of LR would sustain with enough copepods. So... I sympathy bought one, which I will never do again I figured it was definately going to die there, and my 75 gallon tank that has copepods crawling on every surface imaginable would give it a better chance. Problem is, it won't go eat them. There are probably 10 within the square inch of the glass in front of it, but it just won't eat them. Advice w/out grief please?
