 Zoantharia is an order of anthozoans that, for the most part, look very similar to one another. Taxonomists are still trying to sort them all out. Many members of the suborder Brachycnemina could be missed due to their cryptic nature or simply because some are so scarce. We last reported on the discovery of a new brachycnemic zoantharian about a year and a half ago. Now, two more species have recently been described by researchers from the University of the Ryukyus, the Japan Agency for Marine Science and Technology and Tropical Biosphere Research Center. Brachycnemic zoantharians occur in shallow waters in tropical and subtropical regions. Mainly zooxanthellate, they are common on coral reefs. At present, the suborder includes the three families Zoanthidae, Neozoanthidae and Sphenopidae. Only one genus of the family Sphenopidae, Palythoa, can be found in the Ryukyu Archipelago of southwestern Japan. Sphenopus and Palythoa are the two genera of the family. Sphenopus is azooxanthellate and is solitary. It occupies soft-sediment substrates, typically without firmly attaching to a hard surface. Palythoa is typically colonial and zooxanthellate (like most other brachycnemic zoantharians). It lives firmly attached to hard reef surfaces. Recently, new members of the genus Palythoa have been discovered in the Ryukuyus. They are a bit unusual. … More:

Top 10 Zoanthids and Palythoas for Reef Tanks

My FB Page: https://www.facebook.com/coralfish12g http://reefertees.com/ In this CoralFish video I am going to be giving you my list of the top 10 Zoanthids and Palythoas for reef aquariums. I tried my best to base this list of popularity, price and input I researched online. If I used one of your pictures in the video let me know in the comments so I can thank you!

Why are Zoanthids So Expensive? The Zoanthid Debate

My FB Page: https://www.facebook.com/coralfish12g In this coralfish12g video I am going to be talking about the great Zoanthid debate. There are always fads in the hobby and right now one of the biggest is the selling, trading, buying, and collecting of rare Zoanthids. Some people are sick of other hobbyists creating rare sounding names to match barely different color variations. They don’t understand this craze for Zoas with special names. Others love that aspect of Zoanthids becoming collectors who can sell them to create additional revenue from their reef aquariums. So what do YOU think about this debate?

The Polyp Craze, a Look at Why Zoanthids and Palythoas are So Popular Even After All These Years

Sunny delight Zoas, Photo Credit: ReefKoi Corals In this hobby we see coral and invert phases come and go. From clams to chalices and even maxi mini anemones, it seems like they all go through a lot of initial hype then slowly decline in popularity. One of the mainstays in the hobby have been zoanthids and palythoas, which have been the craze for quite a while now. They have been in demand for what seems like an eternity and they do not appear to be getting less popular. Instead, it seems like they’re constantly on the rise. Zoas and palys are highly favored in the hobby by both beginner and expert reefers alike. They don’t require much in terms of care like other specimens and they grow under many types of lighting from T5s to LEDs. Polyps grow at the bottom of the sand bed or on your highest rock. They don’t necessarily need to be target fed like other corals and they also do not require us to dose things like calcium.

I’m reporting from an ongoing battle that started few days before the Spring swap. My aquarium was in its high peak, every citizen of that little coral nation seemed to be going on with its life and there was no sign of any distress in its structures. But, as I soon would find out, it was just a calm before the storm…

History of War

  A little history before we move to identify the enemy. I’ve been keeping a reef tank since January 2010. I’ve tried to do everything as planned, and after many months I could say most of the plan went well. But that’s not important right now. A few weeks after I set up the tank, new residents started to appear in my little piece of underwater world. I still remember the day I first saw a little clam that crawled from from somewhere in the darkest corners of the live rock. Then a new little invertebrate appeared out of nowhere- a small starfish! I was very excited seeing such a odd-looking living creature (I came from the freshwater side of hobby, where there are no starfish), then fascinated by the way it slides on the glass, and finally I started to get concerned about its place in my aquarium. “Friend or foe?” I asked myself, memorizing horror stories about fish-eating mantis shrimp, assassin crabs, stinging anemones and other non-reef safe animals that can crawl from the live rock in its process of curing. So I started my research… It turned out that approximately 7 out of 10 people (of which at least half were being considered as an experienced and reputable aquarists by their communities) who kept them, never had any problems with them. Two out of ten reefers warned that some of them may eat zoanthids. That remaining one person had, or at the time was having, an issue with them. I calculated the risk and let them stay, partly because they were so small and innocent looking, and partly because they fascinated me. Also, I was proud they stood alive in that immature tank I had. As time passed, that one Asterina starfish I had spotted earlier multiplied. Then I constantly noticed more of them, although never in alarming numbers. They didn’t bother me at all; I found them cute, rather than anything I should be concerned about. They stuck to my rules and played modern citizens, but what I didn’t know is that at night they were secretly conspiring by candlelight (sort of).… More:
