Not many things look better in a reef tank than a red scroll. It's almost impossible to get true red scrolling montipora in Australia. These small frags will give some reefers an opportunity. They are small and not cheap but they will grow.
Small size frags are about 2cms, medium about 4cms
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.
