is this a parasite?

[eche]

Hi guys, i just moved my 6" motoro from 6.5ft FGT to 7ft glass tank.. Water parameters are perfect, Ph 7.8 , ammonia 0, nitrite 0 , nitrate 20.. Just now i realise when i turn off the light during the night time, it was doing chin up, and i was shocked see this "brown" things under its belly. It was eating greedy, tankmates are 2 other rays, 2 silver dollars, 1 albino pleco, but there is no such "brown" things under their bellies (rays).. Is it a parasite? Should i be worried?

Here is a pic to show u guys.. Thanks for the advice

Yup, spots.

My motoro has 2 spots just like them, not as dark though. As long as it is eating, it will just be fine.
