Its not often that I catch him so close to the front of the tank like that. Shrimp are not hard to care for. I don't feed anything special, I just let them scavenge as they will. I have an amano shrimp in my 55. He lives in a piece of drift wood and the only way I even know he is still alive is I see his molt every so often. I can count the times I have seen him out and about on one hand.
