Want to get two of these also maybe two razor musks do they mix and get along fine? Plan on geting big tank minimum 55gallons(probably def bigger) and want to make it very lively. My main question is though what other aquatic animals can you keep TOGETHER to coexist with these turtles? Which breeds of fish? How bout crabs/crayfish? What types of algae eaters to keep it clean? I want some diversity in the tank you know, turtles/fish/crustaseans but which coexist?
