I have been researching turtles the last week. The only ones that really catch my interest a three striped mud turtles and Mata mata's. I only know the basic care of each, but I have few questions because of conflicting information online. First, the three striped mud turtles. Do they need a basking spot? Some places say they won't use it others say its a requirement to have a land area and basking rock. Also, can they live in shallow water or not? Next, the Mata matas. I can only assume these are not begginer turtles by reading the articles I have, and I have zero experience with turtles, so I probably won't even consider them too much longer. Anyway, my question is, isn't it dangerous to feed turtles guppies and goldfish? Because of parasites? I'm sorry if I sound so dumb, but please be aware I'm very new even to researching turtles.
