hey hey.. i have an albino frog i keep in a 20 gallon tank...i put down some gravel and put about 4 inches of peat on top which the frog likes to bury himself in.. i planted a small fern, succulents, and a bromeliad which he likes to hide behind... to keep humidity high i just just keep the peat damp and cover the tank with a piece of glass.. its like a rain chamber... i have a dim plant light for daytime and i use an under tank heat pad..
