what kind of acan is this?

[Blitz99]

lord? echinata?

it's very fleshy and swells up a good deal...

 

[Blitz99]

and while i'm at it.. how bout this one?

Hillae and enchinata

 

[Blitz99]

hillae? i've never heard of that... thanks for the ID.

 

[ViPeR_930]

Both echinatas imo

 

[All Delight]

both are echinata

 

[Duce]

Agree

 

[al abaqueta]

I think that Hillae is a very good guestimate for the 1st one, and echinata on the second one. Both very nice corals.

 

[thecichlidpleco]

I think echinata for both, but the polyps on the first are quite large for echinata

 

[Blitz99]

i'd be very surprised if they were both the same... the second one is very "hard" and does not swell up, the orange one swells up a great deal.

This is a few shots of my Hillae acan colony.
Polyps are irregularly shaped, about 1/4 inch to 1/2 inch across and have very spikey ridges on its skeleton.
They swell up pretty fat during the day and their polyps form distinct rings as they extend out.

In my experience, enchinata tend to have a very uniform size and shape to their polyps.

Looks like echinata and subechinata.

I think the first one looks like a subechinata the second ones coloration looks like alot of rotoundoflora's Ive been seeing with the orange ring, but could be an echinata. Subs an ech's look virtually identical but if you go to http://www2.aims.gov.au/coralsearch/coralid_search.php
and look at the skeleton display between the two there pretty distinguishable.

1st echinata
