Hi Pufferpack, I have the African Dwarf Frogs. They only get about an inch in body length. The African Clawed Frogs do get up to about 5 inches (I think). I'm now having problems, as i had to clean the tank and change the substrate (the frogs can ingest the small gravel). My male, who sang the first four nights I had him is now not singing and the pair haven't eaten in three days (they can go 10 days w/out food). They are great fun, and I have contacted a frog 'specialist' concerning the problem I'm having. How are yours doing and what kind of fish are you keeping them with? The cories are good, so I've heard. What are you feeding your little frogs? Mine were loving the frozen brine shrimp (before the tank cleaning.) Thanks for your reply!
