Oh! I would be the person who suggested that! but I didnt say he'll be stressed out, just easier to take care of and monitor when you need to since they it is rather hard to check on their status when in a giant tank (comparative to their size). Especially since you just got him, I thought it would be good to monitor him for any possible issues that might crop up. Sorry for the mis information! =P I'm all for letting him out whenever you're ready!
