Aesop;3036092; said:Probably about 2 inches at most. The single is only about an inch. They have more coloration, just were new to the tank when I took the vids. The single has like brown stripes all over and the pair has blue iridescent lines and a red striped tail.
They look exactly like this picture when their colors are bright. Note that this is not my picture, but fish that look pretty much identical to the pair I have.

I hope they're Geophagus tapajos orangeheads though...those guys look nice when they're adults!
The one in the picture has a dotted pattern on its tail....
