Is my pleco healthy?

Hello. I'm pretty new to keeping plecos and this lil guys in our big community tank. I'm unsure if he's getting enough food. I've read the descriptions on how to tell and it seems to boil down 'is it skinny'. Sold to me as a Super Red Bristlenose Pleco from an individual.

Does my pleco look skinny/under fed? What's your favorite food for you pleco?
