By Charles & Linda RaabeMactan Island, The Philippines © 2009  ALL RIGHTS RESERVED     I have never found a crab yet that has hitchhiked into my tank that I would consider reef safe. The only crabs that I consider to be truly reef safe are the commensal types such as the porcelain crab and coral crabs. The only reason such crabs can be considered reef safe is that they never leave their hosting spot.…

By Charles & Linda RaabeMactan Island, The Philippines © 2009  ALL RIGHTS RESERVED     Most of us think of snails and slugs as being harmless grazers of algae but the vast majority of those found as hitch hikers frequently turn out to be very predatory. Cowries are a good example.  There are very few nudibranch that are reef safe and just as the snails, those found as hitch hikers are most likely a predator with…

  By Charles & Linda RaabeMactan Island, The Philippines© 2009  All Rights Reserved      While it is not usualy important to identify a starfish or sea urchin down to the species level, it is important to determine its family or genus.  The starfish groups have a large diversity with most of them not being suitable for our aquariums.  The same can be said of the sea urchins.  STARFISH ARTICLES SEA URCHIN ARTICLES OVERALL STARFISH…

While few are large enough to make out any details, the use of a magnifynig glass…

 By Charles & Linda RaabeMactan Island, The Philippines © 2009  ALL RIGHTS RESERVED    The vast majority of worms will prove to be harmless or at the least, a predator of other small worms and pose no threat to the larger life forms that we place in our tanks. Of course there are exceptions. While some worms can grow large and seem threatening they are in fact a vital part of the clean up crew, taking…

A few thoughts of my own on this subject.    For the sake of using correct terminology, Live rock is NOT bare rock that has some filtering bacteria on it, I don't care who…

By Charles & Linda RaabeMactan Island, The Philippines© 2009  All Rights Reserved     I have never had a tank that once live rock was introduced a wide variety of sponges did not appear seemingly out of no where, in just about every color and shape imaginable. Most are transitory, making an appearance and shortly disappearing again. Most likely our systems are lacking the proper environment for their long term success. Sponge and Tunicates also…
