I'm going to get a new 55g tank and I'm going to plant it. My question is what kind of aquatic turtle Is the least aggressive, smallest size, least damaging to plants, low bio load, and not likely to eat my smaller tropical fish (such as young tiger barbs), and all within a reasonable price? lol loaded question I know. I've heard good things about Mississippi Map turtles (males under 5" full grown) but I have no exp. with turtles in general.
