Gymnogeophagus gymnogenys yerbalita
I bought 3 at the local aquarium club auction, looks like a male and 2 females based on the size difference.
The tank is a 75 gallon, there are 4 balzanii, 2 'paso pache II', a Crenicichla minuano pair, and the yerbalita. A bit crowded? No aggression right, I may upgrade or sell the paso pache II in the future.
female in front, male in back, the size difference is obvious

male

shiny scales

male + 2 balzanii

one of the females, they are pretty small

I was initially worried that the females were small enough to get eaten by the male minuano, but, being an insectivore, it has a relatively small mouth. If they don't do well I can move them to my 29 for a while.
I also picked up two big yo yo loaches to go with the group I already have in another tank.
