Will take a pic of my two hoeksemai frags this upcoming weekend and post them here.
Regarding the abratonoids, I think ensuring good water quality is even more paramount for it vis-a-vis other acropora species in order to maintain its red colouration. Of course, if it is placed less than 12 inches away from a 400W halide bulb with a lumenarc reflector, one can possibly get away with slightly less pristine water quality - that's the advantage of high powered lighting.
The interesting thing about abratonoids is that depsite its fussy requirements, it is an aggressive acropora and in my tank has burnt two of its neighbours i.e. a.prostata and a.sameonsis - its polyps can extend considerably when lights are off. Hence, I had to relocate its closest neighbours away by another inch or two.
