Heya
First off, they're called rami...But gill fluff works well
One thing that comes to mind immediately (and has been the cause in both occasions I've had this happen) is water flow- how strong is your filter's output? Is there any way you can reduce the flow?
Just in case, could you post:

Temperature?
pH?
Ammonia?
Nitrite?
Nitrate?
Tank size?
Tank Pics?
Type of filter and how it's set up?
What chemicals you've been using in the tank?
Diet?
And most importantly, pics of your axies- front on, from the side and from above if possible so we can see what's happening?
Hope to hear from you soon!
