Could be altifrons or dicrozoster, there are a bunch of geos that look pretty similar. I'm not a geophagus expert, perhaps one could chime in.lol wow that's great. Their good. Expensive but great.
So if it isn't a true surinamensis. What is it
What is CoA
CoA is Cichlids of the Americas, online cichlid distributer specializing in central and south americans. AF gets their American cichlids from them, though they will get some of the more common ones from other distributors.
Yes AF is pricey. Still worth it to me because of the care they put into maintenance on the tanks. Whenever they see a single spot of ich, the whole tank is quarantined and they won't sell a fish out of it. The employees all have to take tests on different types of fish, and generally all love aquariums. Was a pretty cool place to work.
