Patch on the belly of motoro?

[Calvin4924]

I recently got a small female motoro (6-7" disc) from my LFS. She'd been there for months, was eating, and overall seemed very healthy. She's been in my tank for 5 days and I noticed a long patch on her stomach. She still has quite the appetite and is moving around like normal. I haven't kept Rays before and want to know what it is I'm seeing.

Water parameters checked out.
Tankmates are 3x 8" peacock bass.

Thanks

do you have an exposed heater in the tank?

I do ?. For the most part it is behind some wood and hard to get to but she definitely could've squeezed back there. I will go fix that immediately. Thank you for the quick reply!
