Hello, this is my first post. I have a 75 gallon tank and bought fish about 1-2 months ago. I purchased the last Geophageous at my LFS and they said that it is a Gold dust Geophageous. I googled a gold dust Geophageous when I got home, and I struggle to be confident that it is a gold dust. I'm hoping someone here can identify what fish this is for me. It is not old so perhaps it needs to mature to gain its color, but I see no real gold color to it.

I believe the species name for this fish is "geophagus" sp Altu Sinu. meaning its a undescribed species. Looks to be from the pellegrini clade which can be tougher and like harder water than your satanoperca or suriname type geos.

I've kept the red humps and the pellegrini- they are big, bossy and very pretty with a more angular body that your typical geos. i kept mine with andinoacara rivulatus this was a 180, in a small tank like a 75 you may be only able to keep a pair or single male from the species longterm- not to say you couldnt have other fish.
 
That head definitely looks Satanoperca or red hump to me...but something seems a bit off.
