Presented by Charles & Linda RaabeMactan Island, The Philippines© 2008 All Rights Reserved As great looking as some clams can be, they also seem to be a difficult species for new hobbyists to maintain. I believe this is greatly due to the poor water quality that most new tanks encounter.

Presented by Charles & Linda RaabeMactan Island, The Philippines© 2008 All Rights Reserved There is nothing that will catch a visitors eye faster than an anemone with a clownfish snuggled in it. I have had the fortune of having had a few different species, all of which did very well for me, but not for my reef aquarium.

Presented by Charles & Linda RaabeMactan Island, The Philippines© 2008 All Rights Reserved While providing great clean up services of algae when all other members of the clean up crew refuse to eat it, I feel they are a last resort and should only be kept in a reef aquarium under supervision, in that I mean keep an eye on them.

Presented by Charles & Linda RaabeMactan Island, The Philippines© 2008 All Rights Reserved As Beautifull and interesting as they are, sadly there is very little known about the multitudes of species, what is known is that they all have very specific food sources such as only one type of sponge, coral, algae and so on. Given this, it is almost impossible for us to provide such specific diets in our tanks. But all hope…

Presented by Charles & Linda RaabeMactan Island, The Philippines© 2008 All Rights Reserved Although some hobbyist find crabs as interesting as I do, I have also learned that there are very few crabs that I would consider to be reef safe, about the only one that I have had experience with and can say they are totally reef safe are the commensal species, those that host either corals or anemone .

There are a great many species of snails that are not found in the rocky habitat that most reefs and our aquariums are. As…
