yup I moved a betta . . . however the labarinth thing and the temperature flexability made it a little simpler. I was going to move the 900 miles with the whole tank - a school of corys a few platies, shrimp, but i found them a home at the last minute with a friend who's little brother accidentally drianed his whole tank while he was away-all his fish died it was sad. if you ever have to do it again there are some helpful hints in the articles section of this website!
