I posted a little ID info here - http://www.monsterfishkeepers.com/forums/showthread.php?t=237890

Cool, thanks. I may be looking into getting a male soon. If you ever think about letting any go let me know.

wow.. awesome...I have two females.. I need a male also.. let me know if you would spare one!!!!!

 

[zero_go]

I new here but like to help.. anyhow i think its a Guianacara sp. "Rio Caroni"

Possibly, but the relative thin and complete midlateral bar suggests that it may be a geayi. These guys all look alike...

According to Kullander's guide to this genus, true geayi have a wide lateral bar. Plus true geayi do not have those black dorsal lappets.

Based on the pic LouieV posted, I'd say Guianacara cuyunii. It could be G. oweroewefi as he suggested, but in that particular pic there is no midlateral spot which G. oweroewefi does have. And as the link peathenster posted state, that midlateral blotch would be on or below the lateral line.

But these fish can be a pain in the arse to try and identify.

Yep - cuyunii has the thinnest bar (~3 scales wide). Does it have some kind of greyish membrane between the throat and the opercula?

Yup, 3 going down to 2 (vs 4 down to 3 in the others) ... the guide doesn't mention the membrane, Kullander uses a combination of the lateral bar, midlateral blotch, and black lappets to distinguish between the species. I can type it up and send it to you if you want peathenster.

Thanks. I have the 2006 paper in Copeia and figure 1 is pretty informative... think I'll get sued for posting copyrighted stuff?

Or I should just sell my Guianacara group and get it over with

What guide are you two using? This is great info and I'd like to learn more!

I haven't yet ... *lol* I have posted the diagnostic key for them before ... I just make sure I post who created it, and both sources it was posted in (I don't have the Copeia article, but the Dr. Leibel listing of it in a THF article).

Naw, they are neat non-eartheater eartheaters *lol* Keep 'em.

Edit: The key we are refering to is by Donald Taphorn, Sven Kullander, and Hernan Lopez-Fernandez ... printed in the Copeia 2006, No. 3:384-395. At the time it gives a diagnostic key for the then current Guianacara species, so it won't have any described in 2007 or later. A summary of the key was also printed in the Feb 2007 TFH 'Cichlidophiles' article by Dr. Wayne Leibel.
