Thank you all for your quick responses, I appreciate it. I really hope he is just scared from the transport, and hope he'll perk up soon. I have pretty good cover in my tank. 4 plants, and two big logs with plants attached. The petsmart tank he was fine in had no cover what so ever? I really wanted to be a good fish owner, and have decent conditions for the fish I buy. I tried to cycle it, keep the water changed, and do testing, but yet the fish I buy sinks to bottom and looks like he's just seen a shark!
