Anubias Help

Hi,
So I've got a small tank with a handful of neons in I also have a big tank with silver dollars,severums,clown loaches, albino corys and rams.

I had Anubias in my big tank but the Dollars attacked it so I moved it to my small tank with the hope that it would recover and grow. But nothing is happening no new leaf growth, no shoots, no new growth at all . I was wondering am I supposed to cut or trim off the dead and damaged bits?
thanks in advance.   

Hi ColinB
its been in there about a 3 weeks now I think it might actually have grown a bit as now have a tip of a leaf sticking out the water.
Think I will give the dead looking bits a trim though. Is it best to chop or snap as the base is a bit like a rhubarb or celery plant which you pull bits off rather than trim.
