I have a pinkish brown one with yellow polyps and it has always done well for me. Certainly not setting any records on growth, but just chugging along. It does better in my softie tank which gets fed more and under medium lighting (at the least, it definitely doesn't like getting pounded with light). I assume this applies to the yellow ones too.
There is a big one at the critter right now with VERY bright yellow polyps. Sharp looking coral... if only I had the space...
