Hello, this is my first post here!
I am currently setting up a 160g SA cichlid tank. This will be my first cichlid tank. I have kept a few cichlids before, but only rams and apistogrammas.
My plan is to have 1 chocolate cichlid and 1 heros efasciatus. I also want to keep geophagus. My LFS have altifrons and surinamensis. So i need your opinions on keeping geos. Would it work to keep one of each species and maybe a threadfin acara as well?
Or would it be better to go with one of them and keep a group of 5? I was thinking the tank might be a bit small for a whole group of 5 altifrons when they grow up?

Welcome aboard!

Yes you're right once altifron grew to adults the aquarium will be too small.
 
Thanks!
Yes thats what i thought.
So what would be the best option if im gonna keep geos? Would it be better keeping one of each species? Or only one single altifrons whit the other cichlids?
 
In nature Amazonian (northern S American) Geos are typically a social species, doing best as a group, until breaking off a pairs to spawn.
My altifrons easily hit 12¨, so in time, a social group of Geo (4 or 5 could) could easily max ot that size tank alone.

G pyrocephalus might be a better fit for that size tank.
Acarichthys (threadfin) also get quite large, and can become aggressive once mature (8¨+)

Thanks, that helped a lot.
I was also thinking about pyrocephalus but i have never seen it for sale in my lfs. They seem quite limited when it comes to cichlid species.
So in your opinion my best option for geos is a group of pyrocephalus. And if i cant get them i should find some other type of cichlids?
I have also been thinking about yellow firemouth(Thorichthys pasionis) or the common firemouth, and t-bar cichlid.
Im open to any sugestions on other types of cichlids.
