Large Zoanthid Colonies Needed

In recent Reef Threads podcasts Christine and I have discussed the unique beauty of soft-coral aquariums and how they should be viewed with more enthusiasm by hobbyists. As part of our discussions we’ve talked about how uncommon it is to see decent-sized zoanthid colonies. Most zoanthid collectors tend to have a lot of small clusters on frag plugs rather than mature colonies that play a notable role in their overall coralscapes.
   Those discussions prompted me to look back in my archives to see what photos I have of larger colonies. I was surprised to discover that I have several such images. So many that it was a challenge to select a handful for this article.
   Finding and viewing these images confirmed for me that we need to see more large colonies because a large collection of zoanthid polyps is a visual treat. Regardless of the morph, their varied colors add something that few other corals can contribute to a reef aquarium.-Gary L. Parr,,

About Gary Parr

Reef Threads is a podcast and blog that discusses the most interesting subjects from the various forums, blogs, and magazines supporting the reef hobby. Reef Threads is produced by Gary L. Parr and Christine Williams Pasagelis, two veteran reef hobbyists. Gary has been keeping aquariums for most of his life, starting with a 1-gal. bowl of guppies. He has kept reef aquariums for the past 15 years. His current tanks are a 65-gal. LPS and leather reef and a 40 breeder that contains azooxanthellate corals. Gary’s other hobby is photography. He specializes in macro photography and currently spends most of his time photographing coral and marine fish. You can see Gary’s work in the Reefs and Animals sections of his website, You can contact Gary at Christine Williams started keeping fish while she was still a fetus. While the aqueous environment did lend itself to the hobby, it limited her to freshwater species, and so she decided to be born several weeks early. Through sign language, she demanded that her parents convert her crib into a reef aquarium and thus started her illustrious career in marine ornamentals. After completing her studies in biochemistry and molecular microbiology she went to work at “Animal ER” where unfortunately she was not filmed for the Animal Planet channel (though her feet did make a cameo during a rescue segment). She frequently lectures on reef topics including marine animal disease, fish husbandry, human-tank zoonosis, and fish cognition. Contact Christine at
