I think we have figured out these are Paraneetroplus gibbiceps. I am posting new pictures as the colors have changed since introducing these into our tank. One of them is actually standing up to the Oscar now (see picture). The other one seems to has its jaw area change colors to a dark grey / black and then quickly back to normal. Do you agree that these are Paraneetroplus gibbiceps and what’s up with the color change in the jaw area on only one of these two.
