So I started at 6 am working in the fish room and my plan was to move a bunch of stuff around and add another tank I could use to separate my Red Devil from the growout since she's becoming a nuisance and ended up needing to use it to move my pair of Geos because I saw the 2 of them acting very territorial to fish they had been housed with for months without issues, including non-cichlids. Haven't seen eggs yet, but I seen pre-courtship behavior enough times to read body--language and I'm pretty sure they have paired-up at this point. The female was really really REALLY going after my Gymno Balzanii like non-stop to the point she was staying at the surface and the male kept twitching and flaring his fins and being flashy s I think it means you-know-what. How is this possible? He is only 4-4.5" and she is only 3.5-4"......aren't they still too small/young? He doesn't even have a hump yet!

Good luck! I never really liked geos until I saw like almost every species at this one pet shop. Beautiful fish I was so tempted to grab some but maybe in the near future.

Are geos slow growers?

I have found any of the tribe geophagini to be average growers,
took about 3 years fro my Acarachthys heckelli to go from just under 2" to about 8"


Many of the non-tropical species stay relatively small, mostly because it seems growth almost entirely halted during their cool down period
There are almost 25 species of Gymnogeophagus alone


To me, one of the most important factors in keeping geophines, is matching your type water to the needs of the species. If you try keeping soft/tannic water species in hard alkaline water, or vice a versa, their health because an important issue.
I have never been successful at the soft water varieties like Satanoperca, but have done well with Gymnos, the braziliensus complex, the red hump group from west and north of the Andes where harder waters are the norm.

duanes duanes , those Heckel's acaras in the 1st pick look just like the one I bought as "Surinamensis" but have been suspecting it is Altifrons. Any pointers on how to figure out which it is? only thing i'm sure of is it is a female.
 
here's an adult altifrons, I had years ago


much more elongate that the high bodied heckelli, below


I've never been able to keep surinamensus because my water was to alkaline, so I'm no help there. All I can do is post the pics above, and below of the heckelli.
