Good call for any tank below 200cm.but without any other fish except for maybe a single bottom dweller of some sort.
My denisons actually tend to stay toward the bottom and clean the substrate very well. They might starve out a bottom dweller such as cories (mine did). Maybe a surface fish such as a larger gourami would work.I would (5-6), but without any other fish except for maybe a single bottom dweller of some sort. What's the worst that could happen? Once they grow up you decide they need a larger tank!Cool fish.
