A 40B is a 40 gallon breeder tank with dimensions of 36Lx18Wx18D. Called a breeder because of fish breeders using that size (and 30Bs) to breed and raise fish. IMO that's about the smallest you can keep a grown male African Bullfrog. If you prefer to get a 20L now and latter upgrade to a much larger tank like you state; that is up to you. Reason I recommend getting the larger 40B is that buying a tank and accessories (top, filter, heating, light, etc.) once is cheaper in the long run. Also; sometimes the best laid plan to upgrade tank later (for large growing animals) sometimes go awry leaving both animal and owner in a compromised situation.

If your Pixie is calling; it's a male. Good luck !
