    I know this might seem like a dumb question but I’m still pretty new to fish keeping and I have never seen my fish like this. Anyways, about 30 minutes ago I noticed my bristlenose pleco had a fin/ bristle thing (sorry idk what it’s called)coming out of the side of it. So I decided to come here to make sure that it was okay because I couldn’t find anything online about it. I also have a photo of that helps.

    Hi and welcome!

    Was he being annoyed by a tankmate? They have defensive spikes that they can flick out to fend off rivals or predators and it looks like that's what he's doing.

    Don't worry my bristlenose always do that. It's normally when they are trying to 'stand their ground' or are just annoyed by some tank mates. It should go down soon!

    Okay thank you! He was probably doing in because I had just cleaned the tank before I noticed it, since I didn’t see anyone bothering him.

    Mine do it also, sometimes when nothing is bothering it, almost as if they are just stretching.
