ID anemone please

[Delphinus]

(Better late than never?)

Looks very much like a Heteractis crispa (sebae), which you kind of knew by now.

LTA's (Macrodactyla doreensis) and sebaes can sometimes look quite similar. H. crispa can also look quite similar to H. malu although H. malu and M. doreensis don't really look anything alike so it goes to show how variable that species can be.

LTA's are sometimes called corkscrew anemones because sometimes that have tentacles coiled up like ... corkscrews. But not always. But generally speaking you can tell a LTA from a sebae by that the tentacle density is much higher on sebae's than LTA's. If you can see the oral disk through the tentacles you're likely looking at an LTA but if you can't see the oral disk at all through the tentacles then sebae is a likely candidate.

They don't always have the purple/pink dots at the tips of the tentacles.
