Trevor 7/09/03 3:43Clown Fish are enjoying great popularity due to the movie "Finding Nemo" As always, with aquarium Clown Fish, there is an accompanying demand for anemones. Unfortunately, all anemones are not suited for captivity. Anemones and Clown Fish have a well-known relationship. In the ocean, the Clown Fish are protected from predator fish by the stinging tentacles of the anemone. Clown Fish anemones (of the species Entacmaea, Heteractis, Stiochodactyla, Macrodactyla and Crptodendrum) have very specialized requirements. Some are from shallow water and need direct sunlight. All are capable of crawling around the tank and injuring themselves. All also need direct feeding in large quantities. And even aquarists who are able to meet those demands are not able to keep anemones alive. When an anemone is not given the chance to produce offspring, it is a tragedy. If we keep up these destructive collecting practices, there will be no anemones left in the ocean. They simply do not reproduce quickly enough to keep up with the demand of the pet trade. Anemones should be placed in the same category as whales, panda bears and black rhinoceroses: these huge beautiful animals cannot be killed indiscriminately. Imagine a vendor trying to sell baby panda bears to keep as pets in a living room. This vendor would find himself the target of million dollar lawsuits, and would be reviled by animal-lovers everywhere. Keeping pandas in a living room is ridiculous and cruel. Yet, when many large anemones are taken and put in aquariums, it is the exact same situation. Perhaps the worst part of this oceanic pillaging is that captive Clown Fish do not need anemones. Do not let a fish store or an "expert" tell you that Clown Fish need an anemone in an aquarium. They absolutely do not. In the aquarium, there are no Clown Fish predators, and so the protection from the anemone is unneeded. In captivity, there are many other cnidarians that make excellent hosts for Clown Fish; SallyJo has done extensive research on Sarcophytons as an alternate host. We have Clown Fish here at GARF that have even taken up residence in Xenia and mushrooms. We must not take any more large host anemones from the ocean. It is absurd that we do this in the first place, since captive Clown Fish need anemones about as much as they need a bicycle. Despite all the evidence of anemones dying in aquariums, they are still offered for sale. When I was doing research for this article, and typed in "carpet anemones" to the search engine, web pages offering these animals for sale came up often. This is, quite simply, disgusting. You may be asking yourself, "what can I do?" As a hobbyist, there is a lot that you can do to stop this injustice from occurring. These anemones are being taken from the sea in the name of the hobbyist, because there is a demand for them. Do not buy an anemone. We aquarists have power in our pocketbooks. If we refuse to support the irresponsible pet stores and suppliers that collect anemones from the wild, they will stop buying anemones quickly. Even if you have no interest in buying an anemone yourself, be wary of shops that carries them. Tell the owner that you refuse to support the killing of anemones. If we work together we can protect the ocean and end this abhorrent practice. |

WhatYouSea sells coral frags on the internet for people with saltwater aquariums. A coral frag is a small piece of live coral that a person can add to their tank,and grow out. The niche should be blogs related to saltwater aquariums, and coral propagation and sales. Let me know if you need more information.
