Ok so i couldn't resist, I was at petsmart getting some cartridges for my filters and walked by the fish to see what they had like always and the little guy swam to the front of the tank and had that cute little grin they always do so I caved in and bought him, he is no bigger than by biggest emperor tetra, maybe 1.5 - 2". Anything I should know that's especially important? I know the basics and stuff, and he will be going to my 75 in due time. Any specialty food they like to eat?
