I'm not sure what to do now. First my RES, Atticus, would randomly attmept to dislodge the filter from the tank. He stopped though for a week now at least. Now he seems to enjoy removing his dock. This morning I woke up and the dock was in the middle of the tank and he's under it just looking at me like "Hey mom look what I did!"
Background on my turtle: He's 4 years old and at least 6 inches long. I took him from someone on my mom's church forums who couldn't care for him anymore. He was in a 10 gallon tank
I'm freaking out because google tells me he can trapped and die under there but I think he's too big for that. Help please!
