I cut a 8-16oz plastic cup in half and used it as a baffle for HOB (taped across outflow) for betta and lilies (if you're using canister someone else could chime in).
Just some recommendations:
1) Nitro-zorb or nitrate absorbing plants.
2) These fish also prefer a darker tank setup, some floating dwarf water lettuce, frogbit, or water lily?
3) Might want to add airstone timed for night operation (for plants)
