Hi folks. I've got an (I believe) Albino African Clawed Frog. Little critter bought from Wal-Mart a couple of years ago. Wife loves frogs and she loves this frog. Anyway, as far as I've seen over the years, there is nothing at all that you can put in a tank with one of these. It will eat anything. Or kill anything. So I can't get anything in there so far to clean. I need cleaning suggestions other than constantly sticking my hand in there to clean the tank for the family. Typical freshwater algae growth, etc. on substrate and walls. EDIT: tank is about 3 or 4 gallons, I don't remember. It's an Aqua-Tec setup from Wal-Mart. Thanks for any help!
