Silver dollar? Or something else?

[Hendre]

Popped into a shop earlier and found this weird looking "silver dollar". Is it one or maybe something else?

Looks like a malnourished or a deformed SD.

SD for sure. Think it’s the angle that it’s swimming. The eyes are big on some SD species.

I'm more concerned about the body shape

Can you get a pic with it from the side?

It’s m. altidorsalis, i believe, and seen them with a similar body. It maybe a bit thin like tlindsey mentioned. As long as it has a good appetite then wouldn’t worry.

Def not a piranha, sd can look pretty funny if not fed right
