ok, yes its my tank. I seen these at petsmart of all places and got all 3 for under $7 but i know there worth more just not sure how much more. They were labled as Geos. Yes they look like this most of the time but when the light hits them they have a nice shimmer to them with red on their fins. Had them for 2 weeks.
When they are young they are hard to tell apart. Could be G. altifrons or abalios since those are they most common. I'd check back once they get an inch or two bigger
