Pseiidocorynactis spp. are very beautiful, fairly large, coral-limorphs that are the favourite of underwater photographers the world over. The large, conspicuous, often brightly coloured acros-pheres of Pseudocotynactis catibbeorum are, unfortunately, only visible when the tentacles are extended at night. During the day the polyps are completely closed and retracted. The polyp base can be up to 4 cm in diameter. When fully expanded they are trumpet-shaped with the column differentiated into a scapus and scapulus. Their well-developed sphincter muscles allow them to fully retract the oral disc and tentacles presenting a mammiform shape (den Hartog, 1980).

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.
