Rio Negro focused Biotope Tankmates

[FrankNFigs]

I am building a Rio Negro focused biotope tank. Although I am focused on heckel discus, I do want to choose correct dwarf cichlids as tankmates. The tank is 500 gallons , 8’x3’x3’.

As of now my possibilities are:
-Biotodoma Wavrini
-Dicrossus Filamentosus
-Dicrossus foirni
-Apistogramma diplotaenia
-Apistogramma Biotoecus
-Apistograma mendezi

Any other recommendations on species and pairing are welcome

Thanks.

-Apistogramma Biotoecus

Biotoecus is a genus of its own. Typo?

Biotoecus species are a quite small and all species need a lot of open sand. I would not combine them with Discus.

D. foirni are rearely available and I would rather give them a tank on their own to shine. The deserve the spotlight.

@anewbie has Discus with D. filamentosus, he might have further info for you.
