I am interested in starting a RES tank. I have a 40 Breeder that I was planning on using for two of them. Is this enough room? (the dimesions are 36"x18"x16"
Also, what kind of lighting requirements do I need? I'm assuming I'll need a basking lamp of some sort and a flourescent light for UVB rays. Can I use a regular florescent light or do I need a full spectrum light? I need a submersible hearter as well. Do i need a cover for it so the turtles don't burn themselves? Do turtles need a substrate? Some of the pictures on websites I've been looking at just show a bare tank. Other things I've read say they need about the same amount of gravel as a fish tank. How much matinence is a turtle tank? Is it like a fish tank changing 20% of the water every 2-4 weeks? I read something that said you should change 25%-50% every week. Thanks for the help.
