no white sun corals as far as i know, but it could be a white cup coral.
look up Astrangia poculata, for example...

This is what I am referring to... These are images off google not something I personally have.

I have seen both of these images called white sun corals but I figured I would ask the pros as my google search has lead me to absolutely nothing substantial.

Sun corals / Cup Corals are popular generic names used to describe dendro/tubastraea like corals. Sometime we attach a colour to describe the coral more fully but colour (for the most part) is not a unique species characteristics. You can have orange, yellow and even reddish tubastraea coccinea. Foods/ph/water chemistry and temperature (or even genetics) may be reasons for colour differences.

There are over 70 species in the dendrophyllia genus - most of which I'm sure we haven't seen in the trade. So there definitely can be white "sun corals".

The 2 photos you posted - the one on the left looks like a white variety of an arbuscula (could even be an altogether difference species) and the one on the right looks like it could be a variety of the many japanese sun corals - (hardly traded here) or even a balanophyllia sp.

Noy- thank you so much I can't thank you enough for your detailed explanation! I recently purchased what I was told repetitively was a sun coral, it looks so much like the second picture that it's unbelievable, I wish I could get a better image of it. I am so in love with the this piece and it is in my personality to want to know everything I can about things that I'm interested in. I have posted several threads and gotten several answers. I like to be educated about things and this is the best response I have received anywhere! Thank you again for taking the time to explain it to me!!!

Yearssss ago I actually had a "white" tubastrea baby. I gave a frag to someone on another site just in case I lost my mini colony (which I did) and lost contact with the person I gave the baby frag too. I'll try and look on my old computer for pics to post.

I have what looks like a white dendrophyllia. The orange colour is a meal of shrimp eggs it had.http://http://rt67ghy.imgur.com/all/

Oh that is really pretty! My dendro's tentacles never look that round and bubbly though.

Advanced aquarist has a great article on sun corals which includes pics of different species. A related species of deepwater coral is solid white - stunning.

I can't tell fully from the shot but the picture is showing a soft body and its attaching to the rock not with a calcium carbonate skeleton. It looks like a majano anemone or something in the corynactis/pseudocorynactis genus.

If it doesn't have a hard skeleton underneath (observe it when it fully retracts) - then its probably not a dendrophyllia/tubastraea coral.

The white part is hard skeleton. The coral is recovering and so it was showing mostly skeleton. Now there's some flesh growing from the top and spreading down which is a pale orangish/whitish colour. I'll post another pic after there's more growth

Here's a better pic showing the orange colour developing. The greenish tinge lower down on the skeleton is algal growth and there are coral frenzy pellets at the bottom; pic was taken after feeding time.

Wow... I wonder if the tentacles will develop any of that color

I got the clear ones off of tampa bay saltwater live rock, the others are my black sun and fathead dendro.

Those fathead dendros look gorgeous. It's a real bonus to get uncommon suns on live rock.

Those clear ones are nice, how long have you had them and have they reproduced?

Thanks. I cheated though my lfs got a order of thier rock in and I bought the one rock when I saw them on thier. I did it again recently but those ones are staying small and brown.

Those clear ones are nice, how long have you had them and have they reproduced?

A few years now. I gave some to one or two people in my club. My tank was down for the past year and I just got them back from a friend who was holding all my nps. All the sps lps etc I had sold off. They grow same as dendros do but seem to need more food than them.
