It's been a while since I've been here...well, hello. I have three problems with my male RES (well, one is just a question). He is about 10 inches long and lives alone in a 75 gallon aquarium with an Aquatop CF500 UV filter and two Aqueon QuietFlow 50 filters. 1. He has somehow inherited a leech on his chin. How do I get rid of it? 2. He is too big for his basking dock. It wobbles around and sinks slightly when he gets onto it. Any tips on making a larger, sturdier DIY basking area? 3. What kinds of fish/plants/invertebrates could I keep with him? He is quite voracious and has demolished plants, devoured schools of fish, and made giants messes out of large crayfish. Are there any especially turtle-resistant species? Thanks to anyone who replies.
