Myleus ID

[OW_Exotics]

Hi can anyone help me with this, got dropped in to my lfs with two standard silver dollars but I’m not sure that it’s the same, seems to have a much more elongated body. Thank you for any help.

That fish is not a Myleus.
It is a female Metynnis. The pictures are not good enough for a better id, but it looks like a female Metynnis lippincotianus, often called spotted silver dollar. Perhaps you can post additional pictures? As clear as possible.
All silver dollars like to live in groups.

The main character of Metynnis is the long adipose fin, as in the picture. Other silver dollars genera have a very short adipose fin.
