Hi everyone. So here's the scenario: I have 4 turtles (2 razorback musks, 1 mississippi map, and 1 yellow belly) currently in a 55 gallon. They're all about 4 inches and do great together. My gf and I recently adopted an abused adult red ear. Is it too soon to mix my 4 with the red ear? The red ear is missing its entire shell except for it's nuchal and one marginal on each side. It is also missing digits on two legs, has partial digits on one, and it's back left leg is good. I will be setting up a 110 and eventually upgrading to a 200+. Will this be an ok community scenario or should I just keep the red ear by herself?
