hello, I will be keeping an aquarium, probably a 120, maybe a 75. I would like to start with fish (parrot cichlids, shoudenti puffer, clown loaches if its a 120, maybe some apistos or kribs, and maybe some Livebearers. I know that turtles are known for eating fish, but can I keep them together if the fish are larger or the same size as the turtle? what species of turtle is best for this (most peaceful)? I was thinking a male diamond backed terrapin (they can live in freshwater), a southern painted turtle, or a mud / musk turtle. I looked at Mississippi map turtles but they seemed hard for a new turtle keeper. what do you think?
