Re: African dwarf frog?
I have an ADF in a 3 gallon and a 5 gallon would be better, I'd say 3 gallon is minimum. I also agree that they are social and are best with some of their own kind. They like to pile on top of each other in little crevices or caves.
They can live with Bettas but I don't recommend it. The frog is kind of jerky with rapid and unpredictable movements, quite the opposite of the Betta. These frogs are tiny and certainly can't eat a Betta.
They would like live food but are lousy hunters with their poor eyesight and do well with frozen food placed in a flat plate with a turkey baster. He'll find it eventually. They will gorge and adults should be fed every other day conservative amounts, but every day while a juvenile.
Remember that they must surface frequently for air so it is important that their tank be shorter than taller. They really aren't great swimmers and need to reach the surface with ease in regards to the height and current.
Mine are quite messy, in my opinion. They tend to find almost all of their food and eat it, but they are poopy and will require weekly partial water changes.
I keep only males to avoid having tadpoles appear in my tank. If you are patient you'll find some mature males in a fish store. At maturity they will have a visible white (or some say red but I've never seen it) spot about the diameter of pencil lead just behind the front leg. Get mature ones, it's ok, they are still only months old. At maturity their body is about the diameter of a quarter.
Their legs are extremely fragile so it is critical that you use small diameter substrate that will not trap their legs between rocks and avoid any decor that may shift, even the slightest, and trap their legs. If stuck, they will drown quickly. If they break a delicate leg they will die even if you try to help them. I've tried.
They are really fun to watch, silly little guys, but they are nocturnal and will provide you with the most entertainment at night in dim light. Mine recognizes me now. :)
