Long story short. It's a rescue that walked in to a power head. It has holes in it everywhere like Swiss cheese. I have had for about 2 yo 3 weeks now. Before it had its accident it was vivid neon pink and upon my recieving it was almost white with holes. So now it has settled nicely in to my sand bed to the bottom of my tank :/. So far I fed it one hole silver side 3days ago and since it has started to color back some.i know how often to feed it but how much to feed it. It's huge. It's legit wider then my 29gal. Foot diameter is about 5-6 inch across!should I give it 2 maybe 3 silver sides?
