As some of you have said he is going to get really big and is pretty mean so this tank is just his home until he gets bigger, then we have other plans for him. I didn't know there were different kinds of softshell turtles so I am going to post pictures so maybe we can get an ID. If you know what he is also please tell me how aggressive he is compared to the other types. He has also started to use his piece of bogwood to hang out on and catch some air so I'm happy about that. I think he just didn't know where it was. I haven't noticed him burying himself at all. He will dig holes every now and again but that's about it. We are using a fairly fine rock substrate. Thanks again everyone!
