Just finished unboxing an order of fish, and what was supposed to be 6 x 1" baby O. heterospila actually is 5 baby heterospila and one...I don't know. Clearly an eartheather of some kind, and not a Geophagus. My first thought was Satanoperca when I saw it in the bag, but after looking at it now I'm leaning towards maybe a Gymnogeophagus? I only have limited Satanoperca experience (S. daemon, many years ago and not this small) and have never kept any Gymnos myself, just know the look. Anyone know what this little guy/gal may be?
