Has anyone had luck using a supposedly critter tank to be an aquarium? some were made to hold turtles and such, but is it okay to be used as an aquarium? will resealing help? some internet sources have had luck keeping fish in a terrarium.. anyone on the forum have input on this?
Sorry I misread the original post. I thought you meant the Kritter Keepers which go up to about 5 gallons.
Any bigger and I would stick with something built to be an aquarium.
