Species For Tank With M.argenteus

[monoducze]

I have 576L tank (160x60x60cm) with 5 Monodactylus argenteus and 1 Moringua raitaborua. Monos are about 5-6cm. I want to add a new fishes. There is an options:
2x Scatophagus argus + 2x West African mono
1x green scat + 3 mono sebae or 1x sebae + 3x scat
only 3x scat or 3 (4?)x sebae?
3x arius seemani

Which option is the best? or maybe you have other ideas?

I really like scats but would recommend 3 as a minimum

Maybe 3 or 4 silver scats will be a good solution? 5 monos and 4 silver scats in 576L will not be overcrowded? Filtration will be OK, I think.
