Ok, so im getting a new tank for my turtle, its going in my room. Im looking to buy a stock tank, 40 or 50 gallons. My questions are what filter should I get, will the heat lamp melt the plastic, what plants or others should I put in the tank and what size heater do I need and where can I find a top for it? Thanks, thomas and coco the painted turtle(3 1/2 inches, 1.5 y/o)
