It's probably lack of oxygen.
Are you using an airpump? or does your filter have a venturi option? both these are methods to add extra oxygen.
If you don't have either of these options then move your filter outlet(if you can) so that it's rippling the surface.

get some air into the tank ASAP! bristlenose come from fast flowwing rivrs in the amazon basin, picture where you would go white water rafting. Imagine how much O2 they are used too

|Subject: i use venturi and air pump... Tue Aug 24, 2010 12:29 am|| |
i try to use the venturi as much as possible....
though have turned it off for a while and now using a air curtain, and couple of air stones... sometimes the venturi can cause too much algae to grow and adhere to the light reflectors on fluval tanks, so if your gonna go for the venturi drop the water level by about a inch in the tank if you can as it will make your reflectors last longer (thats if your tank depth allows the decrease)
oh and if you cant lift your outlet then put a obstacle infornt of it and you get the same effect...
sometimes i leave a floating fry saver in the tank just to blow the outlet air off as it helps disturb the water
