Ornamental shrimp make great additions to many saltwater aquaria. In addition to being attractive (most are), those shrimp that are symbiotic make for fascinating displays. Many an aquarist has designed a nano tank around such a shrimp, although they also make fantastic additions to an invertebrate or reef tank. Symbiotic shrimp are amongst the most interesting species in the hobby—some aquarists even prefer them to the popular clownfish-anemone relationship (no offence, Nemo).

In this issue of Blue Zoo News, we have shed some light on the utility and appropriateness of certain species of rabbitfishes for marine aquarists interested in a herbivorous fishes for biological control of algae. The star of this story, as the article "Sleeper Cells and Unusual Suspects" (this issue of Blue Zoo News) makes abundantly clear, is a rabbitfish called the White Spotted Rabbitfish (Siganus canaliculatus), which may lead some aquarists to inquire as to where they can get one. While the White Spotted Rabbitfish is rarely if ever seen in the aquarium trade in North America, there are others that should be considered for both their utility and their beauty.
