WYSIWYG from the frag pictured
Full encrusted frag with new branches are about 3-4 cms.
Only experienced hobbyist should consider sps frags and ensure water parameters are suitable before purchasing.. There are no DOA refunds on SPS. They generally survive shipping but they are more sensitive to shipping than zoas so the risks are increase. They do not always survive changing tanks though as they can be sensitive to changes in conditions so make sure acclimation is slow.
