Hey Poly, I'm currently starting a viv build, for a single false tomtato frog and a seperate on for some FBT's. I'm using a 6 gallon faunarium for the FTF, and i'm planning on going with a self contained body of water, as like you I don't wish to make this too akin to keeping fish. I figure a shallow tub of de-chlorinated water changed each day should suffice,and with some careful planning should be able to be intergrated into the natural looks of the viv. I'll post some pics once I'm done![]()
