BS pleco looks funny but acts normal

[Killiwondered]

Have a female bs pleco in a 29g planted tank. I've had her about a year now but I hardly ever see her. over the past two months what I've seen of her she has some kind of weird pattern on her back. Here are some photos. Please tell me what you think.

Hmm... My common pleco developed something like this, but it was a milky white pattern. When I went to my LFS, I noticed that most of the large plecos had this same pattern. I'm not 100% sure, but it started when I started feeding him algae wafers.

I'm not sure about those spots but is your pleco a common pleco? If it is 29 gallons is too small for it.

Female bristlenose plecos don't have bristles on their noses if that's what you were thinking.

Sorry I was a little tired when I posted it. She's a bristle nose pleco

Also I did start feeding her wafers about three months ago
