One very grumpy rainbow shark haha! But that is a great idea! I never thought of doing that. I could just throw him in there with his filter and he should be fine because there wont be any other fish besides him. I would have to move him back into the 10 once I start getting other fish though.
Should I take his filter and put it on the 40 for a couple days before moving him? I don't want to shock the crap outta him lol. But then again I don't want him to run out of oxygen either. I'd say he's a pretty tough fish . . He survived me setting up my 10 (before I knew anything about cycling) putting him, 2 black skirt tetras, and 6 neon tetras in the tank at once!
