After getting much input from researchers and native Costa Ricans, here is my tank.

40 gallon Breeder
Stocked
3 Cryptoheros Myrnae
15 Buenos Aires tetras--this fish looks alike to the Astyanax aenus, but unlike Astyanax BA tetras are readily available
5 mollies--look alikes to poecilia gilli, but again more readily available.
Decor
Rocks are placed as if they were in the shallow river
One small piece of driftwood
A gray sound substrate
Temperature: 82
Filtration is an Aqua Clear 110, which provides current to imitate the slower flowing river.
