Actually I am running with a 55 gallon tank and my guy loves it... he has multiple hides, shrubs, proper temps, the right humididty, and has plenty of room to cruise around at night. Two water bowls,,,.... and a very strong feeding response..... And I am going to be getting him a girlfriend as soon as she has had a few meals in her... she was born on the 19th and is not quite ready to come home yet.
