Dark blue zoanthids are a rare, deep-water species from the Caribbean that really light up a reef tank.  These nano clusters will have at least 5 of polyps on them, and each polyp is dark blue through out and is about ¼ of an inch in diameter   The colonies are not attached to any rock, but may have small bits of shells and some sand intertwined about their base, and some colonies may be attached entirely to a small shell

 

The cluster will quickly attached to whatever you put it on, and will begin to send out new polyps once it's stabilized.  They are very hardy and multiply fast.  Medium to strong lighting will be best for these.  Most zoanthids are photosynthetic and will get much or their nourishment from the symbiotic algae living in their tissues, but they will also need to be fed some sort of fine particle food.  In the wild they seem to feed on plankton and detritus, so when they are opened up, try dusting them with the food of choice.

 

We’ve added this line of nano clusters for those of you who want to try some different colored zoanthids without spending too much money.  They are small clusters, so they will fit nicely in a nano tank.  They also ship real well by priority mail, so this is a great way to try some different zoanthids.
