first I can't really make out
second looks like a frogspawn or possibly a hammer, but more likely a frogspawn
third pic looks like the same coral as the second pic
fourth pic looks like a torch (is that the same as pic one?)
They area Euphyllias. The second one is a Hammer (Euphyllia ancora). The first and last images is the same coral I am guessing, it could either be a Euphyllia paradivisa or Euphyllia yaeyamaensis, and Euphyllia cristata (Frog Spawn). The other alternative is Euphyllia glabrescens (Torch Coral).
^I'm not sure the second/third photo is a hammer.. it has some frogspawn looking tentacles as well.. which is why I would guess frogspawn, sometimes they have hammer-like ends on some tentacles..
Sorry there was meant to be 3 different coral pictures but uploaded the wrong picture (rockie) but you're right the top and bottom are the same and two middle ones are the same. Thanks for all your help though.
yeah it doesn't look too healthy, it wasn't in the best of shape when I bought it but i thought it would open out more and come back to life like the other one did when i brought it. What do you recommend I do with it if it doesn't perk up?
