Bacterial Infections In Gigantea Anemones

of the disc, and usually has a more folded disc shape, though that is highly variable depending on illumination. The tentades of some specimens of S. haddoni do move like those of S. gigantea when illuminated strongly. It is possible that S. gigantea hybridizes with S. haddoni.

Natural Habitat: In shallow lagoon environments on rock or in sand or mud, with strong illumination. Sometimes abundant on inteitidal mudflats. At low tide they experience stagnant conditions and may even be partly emersed, though they can withdraw into the wret mud/sand. At these times they may experience veiy strong illumination during the day or reduced salinity during rainstorms. When the tide comes in they are exposed to strong currents that cany numerous food items directly in their path. At high tide they may be in water 10 feet (3 meters) or more deep, though they were nearly exposed at low tide. This means that the light field varies a lot. The temperature also varies with the tide cycle.

Aquarium Care: Delicate. Difficult to keep, but can be hardy once established under the right conditions. This anemone suffers in shipping and often contracts fatal systemic bacterial infections as a result. Treat newly imported anemones with Neomycin at ca. 10 ppm and provide adequate water circulation. Chloramphenicol may be a more effective alternative drug, though it is difficult to obtain and toxic to humans, see chapter eleven. Ideally each anemone should be given a clownfish immediately. The fish seem to stimulate the flaccid anemone back to health. Give very strong light and moderate to strong water motion (at least intermittently). The aquarium should have a sand bottom with some small and some large rocks, since these anemones can occur in the sand or up on rocks over the sand. Must have clownfish partner for best success. Amphiprion percnla and A. ocellaris are best choice. The clownfish will "feed" the anemone, but healthy anemones are very sticky and will take some food items including worms and small pieces of chopped fish or crab. May also be a suspension feeder (Barnes, 1980) that captures plankton via nematocysts and mucus on the surface of its oral disc, passing the trapped food via cilia and tentacle movement to the mouth. When placing the anemone in the tank it is best to put it on rock, not sand, in strong water motion. It will immediately stick to the rock and begin to "walk" to a suitable site, usually staying where the water motion is fairly strong, sometimes digging its column into the sand, sometimes not. If S. gigantea is initially placed on sand with little water motion the base and column are prone to contracting a lethal rotting bacterial infection. However, if the anemone crawls (not just falls) to a sandy bottom and plants itself it will usually thrive.

The COMPLETE guide to Aquariums

The word aquarium originates from the ancient Latin language, aqua meaning water and the suffix rium meaning place or building. Aquariums are beautiful and look good anywhere! Home aquariums are becoming more and more popular, it is a hobby that many people are flocking too and fish shops are on the rise. Fish are generally easy to keep although do they need quite a bit of attention. Puppies and kittens were the typical pet but now fish are becoming more and more frequent in house holds. In recent years fish shops have noticed a great increase in the rise of people wanting to purchase aquariums and fish, the boom has been great for local shops as the fish industry hasnt been such a great industry before now.
