Only problem I saw with the biorbs is the minimal surface area for gas exchange. a light stock with live plants could be ok.

Actually both will end up hurt pretty badly. They will fight to the death, and don't be surprised if the female wins, it happened to me when a male managed to slip through the divider, and got killed by a much smaller female.

i would do a snail and a couple of shrimp in that only.

Biorbs are not designed for shrimps, it uses a special UGF with rather big openings, shrimps will be sucked in there and killed.

My first fish tank ever was a 8 gallon biorb, had 6 cherry red shrimps. They were able to survive, but all the baby shrimps that came later got sucked into the filter and died.

The 4 gallon version works as a betta tank, throw in some low light plants like javafern and anbuias. Will look pretty nice.
