I would have to disagree and say they are Guianacara geayi. We have had them many a time in our store and they are much easier to come across than Guianacara sphenozona. In fact, out of all of the lists of fish that we can import from various locations around the world, i have never come across Guianacara sphenozona. But have Guianacara geayi, Bandit cichlids and they look excatly like the ones in our store we have at the moment.
Look at images of both species and compare them to yours
Kk, I see your from Wigan on your profile Dont suppose your store is Pier by any chance
I shall msg youwow sorry I had no idea which shop are you at? If your able to say, I travel over to the "Manchester" area for fish quite often so always happy to pick up a new store (unless I have already been to you )
