Could/should I Add Any Other Fish

[liserini]

My tank is 6x2x2. The occupants and their approx sizes are 8" oscar, 8" plec (not sure what type, have attached pic if anyone wants to ID for me!), 6" featherfin cat and 5" RTS. I'm just wondering if I could add any other fish and what would fit in with this bunch! Thanks in advance

The fish in the pic looks a bit like a Gibbiceps catfish.

As long as you keep the tank clean (via regular water change and gravel cleans) then you could probably add a couple more fish. But it depends on what fish you want and you tank maintenance regime.

It look like a sailfin pleco but i could be wrong.

Sailfin plec = Pterygoplichthys gibbiceps aka gibbiceps plec
They're one and the same thing
