Thank you for the input and suggestions!
I am going to leak test the tank and go freshwater native small fish.
I am going to go with aquatic plants below (planted and floating)
and above I will have native plants (floating and planted with roots hanging into the water)
It looks great in my mind's eye, we will see what it ends up looking like.
It may take a month or so, because I am still finishing up my 75g cichlid tank.
Heading to a fish farm this Friday to get them. That is the plan now anyway.
