Weird ancistrus behaviour

[JamesTasker]

My bristlenose catfish likes to sit upside down underneath the log in different places during the day. However today I found it upside down on the sand, as though it had fallen off where it was stuck onto the log using its mouth. I tapped on the glass and it stuck back on but it was back on the sand a few minutes later. It is back to normal now, but does anyone know what could be wrong with it?

Also, it seems to have stopped growing at about 2.75-3 inches. It has very few bristles and i'm not sure why .

Any suggestions/advice greatly appreciated.

I don't know why she keeps falling off, but I think that the reason that it's stopped growing and has few bristles is coz he could actually be a she.

Thanks, that had occured to me which is why the post says 'it' . I thought females still reached about 4inches?

Maybe 'she' was trying to show off! Or was hinting that you should stop calling here 'he' and get her a male companion!!
