Foraminiferans are primitive creatures closely related to amoeba. Unlike amoeba they build a calcareous home. Some forams are unattached and capable of crawling over the rocks, plants or sand. Many are sessile, attached to the rocks by the calcium carbonate they deposit. One common species on live rock is bright red, and it is often mistaken for a small colony of Tubipora, the pipe organ coral which has a skeleton with the same colour (see chapter 1). Homotrema forms small red burs and crusts on the underside of rocks. In living specimens one can see the tiny thread-like pseudopods extending from pores in the surface of the calcareous test. This harmless creature feeds on bacteria and fine detritus which it catches on the pseudopods. The occurrence and proliferation of little creatures like these in a reef aquarium are good signs that the ecological system is diverse and healthy.

Homotrema is a beautiful little sessile foraminiferan. J. C. Delbeek

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.
