i work at a LFS and i found this guy in one of the tanks on our cichlid system. i asked the other employees what it was and where it came from and no one had any idea. he acts pretty shy, but when i stuck him in the tank with all the jack dempseys (3-4"), he had them at one end of the tank and he stayed at the other end of the tank and kept them at their end. he is about 2.5-3". i have asked many people, including customers who have a lot of experience with cichlids and no one has any idea what it is. i even posted on another forum and they couldnt really come to a conclusion. any and all suggestions are welcomed.
