Mike Wise said:What an unusual fish! I have some ideas, but it shows none of the diagnostic dark markings needed to identify the species. It will help if you can answer some of these questions:
Does it have the large black patch on both sides of the body?......Yes
How large is it?.......5cm including the tail
Was it sold with a name?........Ap.pertensis
Can you describe the width of the lateral band?....thin black line
Any guess from which country it was imported?..Brazil,that`s what the lfs owner told me anyway.
Right now, I believe it belongs to the steindachneri-group, but the body is unusually elongate for species of this group. A photo of it showing its fright pattern would be helpful.
