Dart Vivarium Suggestion!!!

[Aminal]

Hi guys, I'm looking for some suggestions.

I'll be getting rid of my alligator peanut soon, getting to big for his home.

First of all I'm an avid animal keeper, with several tanks set up ranging from fish, 18" large soft shell (had him for 13 years), fish, bred beardies for awhile. Also not the kinda guy that buys animals because their cute without any research.

I built a 50/50 vivarium with water fall filter from an old jewelry case Dimensions are 6'x20"x24" roughly 135 gallonish


(the blue center divider has been replaced with glass at an angle to give a better water viewing)


(Filter Fall close up)


(Planted dry side)


(peanut when he was small and cute)

I'm sure I'd have to make some changes to my setup, I'm mostly wanting to know about the water. I know darts don't need deep water or anything but would it hurt them, or should I just mod in a stream or something. Also How many could be comfortably housed in a vivarium this size

thanks for any suggestions or advise you may have.
