I have a Red Ear that is approx. 6-8" around. I have a Yellow bellied that is a little bigger probably more on the side of the 8". I have a Razorback Musk that is about 5" around. I have the three of them in the same aquarium. I also have another Red Ear that is about 2-3" in diameter. I was wondering if he is too small to go in with the other 3 or would he be ok.
