People are constantly requesting help on identifying what kind of SPS coral they have. I often wonder about a few of my pieces as well. In the couple years I've been in the hobby, I think I can accurately distinguish the majority of corals that are kept in the hobby but will get stuck a little on SPS specifically. I think their difficulty to keep plays a role in this. Many times I will see SPS corals with little color or little polyp extension because the corals are not in an ideal tank nor kept under the right parameters. This makes them even harder to identify. Then you have SPS with disfigured branches because they're recovering after being fragged. Or they're simply too small to get a good idea of what the SPS is. The list goes on
Anyway, what am I getting at? Does anyone have a good resource for distinguishing types of SPS? I don't mean acropora vs stylophora. I mean more along the lines of acro millepora vs acro tenius vs acro valida; focusing more on their structure, shape, texture, polyp extension not so much color.
There are several coral databases out there with images as examples but they are a bit simplified. Their comparisons are more SPS vs LPS or acro vs monti which is not really what I'm looking for. If nobody has a link then maybe some of the resident SPS experts here can weigh in. If you have some nice large colonies in your tank that can be of help, post some photos!
