Cool that helps out alot. I didnt think it would be a good idea to throw a big frog in with small ones. seemed like a no-brainer, but i had to make sure. that gives me the idea to divide the 60 gal into two 30s and make a big amphibian section and a small amphibian section, and just keep the dart frog and red-eye in the 20 gal so that i can maintain the heat and humidity they need.
