I had a big softshell in with my jar for a while he did bully the turtle for a bit but he bullies everything so its not new , the turtle did chomp few of my catfishes tails though so I put it in my mates 400l turtle tank he's much happier in there than in my tank he's care free now lol
Wow turtles I used to keep a water dragon as a kid can't even imagine what would happen if it was in with my jar , no lizards , turtles , archers left all eaten by the evil one hahaha
There baramundi silver perch archer fish sooty grinders long fin eel and sawshells turtles and long mech turtles and Gibson water dragons and water
Monitors in the tank its a 7x4x4
I believe 3" in diameter for the turtle is a good size to stand its ground against a jardini. Ive mixed tons of fish with my turtles before. Didnt have much problems until the turtle grew way faster then my fish. No fish died but i was worried they might be snacks so i moved the turtle.
