Nice Guianacara, but they aren't sphenozona. They appear to be G. stergiosi aka sp. Rio Caroni. Which are nicer looking than the sphenozona anyway so nice deal.

Thanks. I have never really been too sure. When I first got them I was told they were Owroewefi. Then later told by the person I got them from that they were Sphenozona. There isn't much reference as to pictures between the species around. What are the key differences between the two?
Owroewefi would be a good guess actually, the only real differance between them and the stergiosi is that the bar fades as stergiosi get larger/age and they just have the spot while the owroewefi bar stays. Yours seem to be fading, hence why I lean towards the rio caroni's ...
100% not sphenozona though, as yours has those black lappets on the dorsal fin, and the spot doesn't sit high enough upon the body. Having a spot rules out geayi and cuyunii.
Here is a quick guide that Dr. Liebel did based on the Kullander-Fernandez paper (which has line drawings, which helps alot).
geayi: wide bar only, no spot, no black on dorsal fin lappets.
cuyunii: thin bar, no spot, black on dosal fin lappets.
oelemariensis: no bar, spot only below lateral line, black dorsal fin lappets.
owroewefi: wide bar, spot on and below lateral line, black dorsal fin lappets.
sphenozona: bar, spot above lateral line, no black on dorsal fin lappets.
stergiosi: thin bar fading as they age, spot below lateral line, black on dorsal fin lappets.

Wish I could change the title..lol. Just curious, how much would they run for at 4"?
Np, neat little fish for sure. I think when I saw them at the LFS, they were about $16.99 at that size. I didn't have room at the time so didn't pay that close attention to the price. We tend to have a really good wholesaler locally though, so I'd imagine depending on availablity anywhere from that price up to $30 or so given that it's almost adult size at that point.
