I wouldn't put any multis in with a betta........
For fish I would go with endlers livebearers.......a couple of ADFs......and you could add a betta to that setup..I have a betta in with endlers and ADFs and they all tolerate each other fairly well...an occasional short chase from time to time, but no harm done anyone.
For the land you could go with redbellied newts, which are supposed to be aquatic, but mine always stay on the land portion. There is a larger fully aquatic newt that looks similar to the redbellies...but it is more aggressive and would eat all your fish and frogs...lol....so none of those if you have your heart set on adding fish.
There are the fire bellied frogs. I see them in Lfs alot.
Anyway, have fun deciding and putting this all together. I have a river tank setup and I really enjoy it !
