Are these Geophagus Pellegrini or Geophagus Crassilabris or something else all together?

I would suggest you send a PM or wait for JK47, Justin to chime in on this. He has experience with both species. There are a number of Geo folks on here who will share their knowledge with ya'.

^can you elaborate on why you think they are not?

I would guess they're not Pellegrini just because Pellegrini are quite rare and quite expensive. I lean toward steindachneri.
 
I got your PM, thanks for sending I don't get as much time to check this section as I used to. (excluding the Geophagus sp. 'Tapajo' in the tank with them) IMO you have 'Geophagus' crassilabris with about 70% confidence, I would be more confident in that ID if they were larger and acclimated to the tank. The adults are known for their dramatic overbite and dark colored lips. If I had to guess based off of their coloration this is their first week in the tank at about 2.5"? If they were 'Geophagus' pellegrini at this size they should be darker with more gold/orange base color and the lips should have an iridescent blue base BUT, that depends on a lot of factors like water quality and hardness. If they were 'Geophagus' steindachneri they would be much more colorful at this size and likely have blue spangling on the flanks for the males at least.

This complex is fairly easy to ID at smaller sizes but the differences can be subtle. pellegrini can be found in the same distribution and provinces as crassilabris which I don't think many people realize which can add to further confusion. Where did you get them? What were they labeled as? Cool find no matter what they are :thumbsup:

I thought about this as well but at this size a common stieny should be significantly more colorful wouldn't you agree? I haven't watched the video's but I don't see the spangling. I could be way off, it's been a REALLY long day. I'll sit this one out snd see what others think. I think a little size on these guys in a couple months would make it a 100%'er.
 
Thanks for the response and the explanation JK

Of course Rodney! To reiterate I'm not 100% on those being crassi's but they are very close, when you add a new species they always look like something else until they settle and put on some size with the exception of a few gimme's. They are 110% in the "crassilabris complex" (humphead eartheaters) though.

^ any answers to these questions?
