As some of you may know I rescued a Ram the other day. I read up on them and it says they like caves which mine has found one he likes to hang out in. Do they normally hang out at the bottom of the tank? Mines pretty much stays low and does not go to the top for food, just kinda lets the flakes fall down to him. He also picks up my gravel and spits it out.....is this normal? What kind of food should I be feeding him? Are flakes and freeze dried bloodworms sufficient? Just trying to get an idea on how to care for him.
