Sea Stars

There are several species of very tiny sea stars (Asterina spp.?) that proliferate vegetatively in reef aquaria. They divide spontaneously and the severed parts regenerate the missing legs quickly. In our experience these sea stars are generally harmless, but we have seen one species eat small polyped stony corals, while another species seems to eat coralline algae. Most species are scavengers that eat detritus. Because of the possibility that some species eat corals we view these sea stars with suspicion. It is wise to hold them in a separate tank with coral fragments to observe if they are well-behaved or not. We don't want to encourage aquarists to annihilate any creature they think might cause a problem. On the contrary, we hope aquarists will become interested in all of the little creatures that make a reef aquarium (and coral reef) a complex, diverse ecosystem.

Brittle Stars

In live sand and from live rock we obtain many species of small brittle stars that are wonderful complements to the healthy community of a reef aquarium. They sort through the gravel and sand, picking out morsels of detritus as their food. They are important in aerating the sand layers and preventing the formation of dead zones beneath the rocks.

Brittle stars living in the gravel are excellent scavengers, sifters and detrital feeders. They are a beneficial part of the "live sand" community. J. Sprung

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.
