Hello, just wanted to post and get some tips and advice from others. I do plan on adding a cap around the edges this coming weekend and then either look into a full enclosure wire top or electric fence. Still Contemplating. This enclosure houses 4 rescue box turtles. 2.2, was planning for 1.3 but two of the rescues I got off craigslist were a pair and I couldn't say no after seeing them in a 20 Gallon aquarium.
