Thanks for all the help like I said I know nothing about them. I had just taken a log out of tank a couple of days prior that they always hid in. So I just wasn't sure.
i think i know what u mean by moving around. ive noticed that on my female bristlenose too. i didnt feel it but i saw it through her skin. its her intestines. if u look carefully after feeding you can see them contracting to move the food through. thats probably waht u felt
