Hi my 8 year old musk turtle has been very weird the last day or so. I moved him to his new tank with my over musk (they have been together sinse I first got them). Sinse I put him in this new tank he doesn't seem to be moving very well. He's very slow and just doesnt look to be moving right. He's spent alot of time of out the water hidden under the sand. The temperature of the tank is the exact same. Everything is the same apart from a larger filter and larger tank. I just thought I'd post some pictures on here to see if I'd obviously done something stupid. I've moved him tanks many times and not had any issues before. He's always been more reserved than my over turtle but never this layed back. I'm picking him up and is not taking any notice to me. Usually he'll be hissing and trying to bite. Any ideas would be great thanks
