LOL. I have 3 that are 11-12 inches and I have two albino ID sharks that are about 4+ inches right now growing out in another tank. The big ones are fatties but the little ones are worse! I bought the albinos at around 3 inches... maybe even smaller... less than a month ago. They eat ANYTHING!!! I have the albinos in my tank full of clowns and they steal the clowns sinking wafers and swim around with them in their mouth till they can rip a piece off. They swallow the piece and pick up the wafer again and continue. They do this to hikari algae wafers. I just got a 2.2 lb bag practically free (25$ for two 2.2lb bags of wafers). The hikari sinking wafers (same deal as the hikari algae wafers) they pretty much eat/swallow the whole thing!!! They get so fat I think they are going to explode or just die on the spot. I think that is why they grow so fast... In my big tank the big guys gulp at the surface when I throw their pellets in. They eat anything too!!! I have fed/seen them eat sliced up cucumber, zucchini, yellow squash, and even chunks of fresh raw garlic!!! Pretty much anything I throw in there. They will jump in front of my slver aro while he is lunging for his NLS ex. lg. formula floating pellets to steal them from him (the aro) and get whacked in the process! It don't even phase them and they swim away happy when they are successful (but it irritates me). Such fatties... they're going to have to go in the pond soon... To think about it the big ones acted exactly like the smaller ones I got when they were that size. FATTIES!!!
