The beauty of the flower anemone, an under-appreciated gem for any reef aquarium

By on May 25, 2012

Reef Builders is proud to welcome Morgan Moore as our newest contributor. Residing in Florida, she is is a professional coral aquaculturist and the owner of the Reef Gardener.

I have always been a champion of the underdog when it comes to corals in this hobby and what is considered the most popular at the moment, often times are not my favorites. Flower anemones (Epicystis crucifer) are a truly underappreciated animal, mainly because they do not host clown fish and most retailers only carry the common tan, white, army green color morphs.

Many people I talk with seem to think all anemones are created equal meaning they are hard to keep, move all around your tank killing corals in the process, grow very large, and will jump into your powerhead at a moment’s notice. The popular clownfish-hosting anemones, like rose bubble tip (Entacmaea quadricolor) and long tentacle anemone (Macrodactyla doreensis), do tend to support this belief.

Flower anemones may not host clownfish but they have so much more going for them. They are one of the easiest anemones to keep and once introduced to a rocky spot in your tank that has good light, they usually will never move. If they do move they creep and will not jump off into the water column. They do host porcelain crabs, sexy shrimp, and anemone shrimp which are very entertaining and interesting to keep in a reef tank.

Flower anemones can be kept in groups, creating a beautiful anemone garden. They love light as their main source of food and can also be trained to take mysis shrimp if you want your anemone to grow faster. Most flower anemones grow to about 5 to 6 in. wide and it takes a long time for most to reach this size without supplemental feedings.

Best of all, flower anemones come in some really phenomenal color morphs. I even received some slightly deeper water morphs this spring from Jesus Larralde of Farside Tropicals that I had never seen before. These particular flower anemones came from about 30 feet of water and preferred shadier areas of the reef compared to the more light-loving flower anemones I usually keep. Though these morphs are quite rare, there are plenty of neon colored flower anemones that are more readily available.

If you are looking to buck the status quo and try something new, do not hesitate to get one or more of these hardy, beautiful anemones that will be a definite standout in your tank.

    Welcome to the crew Morgan! You have always had some of the best anemones around.

    Great write-up!

    Very nice anemones,  not that I even want to get into doing any new type of creatures (I got away from NPS back when NPS weren’t cool :D ) but what sort of substrate/flow would you put for those guys?   I imagine a nice shallow tank with very low surface agitation so you can stare down at these guys all day long, they remind me a lot of the California Sunburst anemone you see in tidepools.

     Well rock anemones prefer to be in rock or coarse aragonite, under med/high light. Just good light is food enough for them. They like medium flow. They do well in mixed reef settings because they don’t move around so you don’t have to worry about them damaging other corals.

    Thanks! I’m so happy to be here. ;]  I’ll be writing on all kinds of corals, husbandry, and anything in between. My next blog will be on clove polyps, so stay tuned.

    Funny you posted this today – two Flower Anemones happened to get placed in my Caribbean reef just earlier today.

    Beautiful nems as always, but are they possible fish eaters like maxi minis?

  • Morgan Moore

     I think only with mandarins and other small perching gobies you might have a problem, but it’s kind of a case by case basis. I have never had a problem with fish getting eating by rock anemones or maxi anemones in all my years of keeping them. Clown fish have known that they do not host and stay out of them.

    Will chemical warfare take place between flowers and rbta or lta’s?

  • Morgan Moore

     I never have any problems with chemical warfare between anemone or corals, I don’t really believe in it. We do run large Euroreef style skimmers in our tanks and have good flow. Of course you will need to give space between different types of anemones so they won’t sting one another.

     This is follow up commentary, I was chatting with some folks on Nano-reef.com about small fish and flower anemones/maxi anemones. One member said this:

    “I have had several dragonets, both mandarins and scooters, as well as
    several different types of perching gobies in a system that has several
    maxis, a rock flower, a giant sebae, and several BTAs, and I have never,
    ever had any go missing that were healthy. A sick fish will definitely
    be preyed on by anything in the tank, including anemones, but we can’t
    fault them for that – they’re doing what they do naturally, which is
    pretty much exactly what we’re trying to recreate in our tanks. ”
