ID this plant? that keeps growing

[chopperman]

Ive got neomeris growing on a few rocks in my DT, have had it for 8 months now. Its calcerous based. It comes and goes, the branches turn white and fall off. Havent seen any problems with it. I was worried at first then I got used to it and now its not so bad to look at. Might not like it if it started overunning the tank tho.
