Any idea what this SPS frag is? It’s encrusting but only very thinly; the base material is not a substantially different color than the rock and it hasn’t thickened anywhere; color of the base is blue-purple (really just looks like the rock underneath.) The polyps are tiny, fuzzy, and pink. The longest dimension on that frag is about 2” for scale. It is growing VERY slowly in my tank, which grows all of my montipora quite quickly; for that reason and the fact that the polyps are much smaller and more evenly dispersed, I don’t think it’s monti. I have it pretty high in the tank around 300 PAR under Radion G4 and moderate to strong indirect flow. I keep my paramenters very stable with auto dosing under the Red Sea Coral Pro accelerated growth parameters (high-end ca/alk/mag) and very low phos (0-0.02) and nitrate (1-2.) I’d like to ID it so I can figure out if it would be ok encrusting the rocks at the base of my acro and seriatopora colonies or montis. Would also be nice to know if it’s slow growing because of placement, or if that’s just its nature. The source it came from didn’t know what it was. Thanks!
