To clean it fill it up with water add a cap size of bleach in it and scrub it down. You can use an ulltra fine steel wool or razor blade to clean off any hard water deposits. Once you're done rinse, rinse, and rinse again. The rule of thumb is 10 gallons per frog. But these guys get big. I personally wouldn't put more than two. They need alot of space. They're going to be in there for their whole lives don't overcrowded them. They'll be more active. It will also be easier to keep clean and you wont have such a huge cricket bill. These guys are pigs. Then you can afford to branch out into other frogs.
