Different variety than the ones we have in the hobby, or different between the two pics? Second pic is the adult of the first as I'm sure you've deduced, but just wanted to make sure...
As for the ones we have in the hobby, there's a lot of the Costa Rican ones floating around, as they're the more colorful of the bunch, so yours will probably look like that to some degree. Your males at least. I was surprised to catch the little one with the big dot but apparently some are just like that, and end up like the big one anyway. The lake population ones tend to be more yellow.

The sarapiqui, where I caught the those two, eventually drains into the san juan (which is where Max Savchuk collected his), and itself drains into lake nicaragua. In asking Jeff Rapps about the potential for there to be more than one species, he said there isn't really THAT much of a difference, and that essentially it wouldn't be worth the hassle of looking into it any further.
While I do advocate for biodiversity in nomenclature and such, and I do believe there's a bit of distinction in behavior and morphology between populations, they are admittedly, as mentioned before, all connected by the same river drainage. If there's any precedent for the potential for speciation, just based on the amphilophus explosion in this particular lake, the best bet for another Hypsophrys sp in my opinion would be lake xiloa, as that's the only place they've been observed babysitting dovii fry. Just opinion till we see molecular data though.
