same size tank as mine, if its one of the complete set up tanks can i recommend purchasing some more hiding places (branches, plants etc) i have just done my tank up including all the bits they gave me with my complete set up, i will say they do need more in the tank, more hiding places and possibly a larger water bowl as i found only 1 frog will sit in it at any time.

i keep 3 whites in mine, shop told me i could easily keep 4. but they also said i could keep another species in the tank as well.

dont take everything they say as them being honest most the time they will lie just to make you purchase and if they can see you feel bad for the others they will try and talk you into buying more.
