The Cauliflower is extremely difficult to keep, probably, in my opinion, the hardest coral to keep... and to tell you the truth, i've never seen/heard of someone keeping it for over 3 months. The longest i've had one was for 3 days. Know they are non photosynthic, and will need to be fed very high amounts of Plankton (Phytoplankton & Zooplankton), which often cannot be supplied in the home aquarium.
Actually, the Cauliflower coral doesn't look anything like the standard colt coral. The scientific name for this is Scleronephthya spp.
Here's a quick picture of the 'Cauliflower Colt,' which as stated above in my posts, contains no zooxanthellae and is extremely difficult to keep:
Many people mistake this coral for the 'Cauliflower Colt' which has the same name. But, as I said before, these corals don't look anything alike. For all I know, we could be talking about two different corals. Here's a picture of the Cauliflower Colt [standard colt coral] (Cladiella sp.)

As you can see, they look almost nothing alike. First, I think you need to discribe the physicle apearence of the colt. Does it look like the standard Colt coral, or the bright colored Cauliflower colt?
I personally think we are in fact talking about the Scleronephthya spp., rather than your standard colt. Whatever you do, do not buy it. This is one coral best left in the ocean...where it belongs.
