I recently moved my channel cat into a 50 gal. tank from the cramped 20. The tank just has river rocks on the bottom and he loves to move them. I am not sure why he does this but I cant sleep and my dad keeps complaining downstairs about it. I dont want to use small gravel because Im afraid he will choke on it. So, should I go with a bare glass tank or what can I do? He just wont stop with his rocks.
