Any ideas on this fish ID?

[Fishymike]

Can anyone offer some suggestions as to the ID of this fish? Pictures are of a pair I traded for at the LFS. To me, they look like some sort of Paratheraps, but the head profile is different.

Thanks in advance,
Mike

They have different shaped and sized mouths and one of them looks like a Nicaraguense.

vieja hartwegi maybe.

The two fish in the first pic look to be different species.

I agree. One of those fish is definitely a Nic.

Sorry about the confusion, it is the fish in the center of each picture. These are two different fish, the fish in the first pic is about 5"+ and the fish in the second pic is 4"+. I'm thinking they are a hybrid of some Paratheraps species.
And yes, there is a nicaraguense in the first pic along with a pasiones off to the left. In the second pic, tehre are some Herichthys "Turquoise"

Chuco godmani perhaps? They appear pretty stressed.

the one on the left in the first pic is actually as hypsophrys nicaraguensis

the other is a vieja, but not sure what.
