Among these iconic fishes is the raccoon butterflyfish (Chaetodon lunula) of the Indo-Pacific and southeast Atlantic, a very hardy species that’s better than your average butterfly in terms of aquarium suitability and even beginner-friendliness. C. lunula would also be a great choice for natural pest-anemone control in reef tanks if it could be kept in such a system safely (but, alas, it cannot—more on this later). Physical traitsC. lunula has “typical” butterflyfish morphology, with a highly laterally compressed body and a pointed snout. Its color is orangish-yellow overall with a dusky hue on the dorsal half of the body and faint diagonal stripes on the ventral half. Like its terrestrial namesake, its eyes are obscured by a black “mask.” Behind the mask is a white bar, and two dark bands edged in yellow extend upward from the white bar.

by Saltwater Smarts | Jan 23, 2016 | Fish, Reef, ScienceWhile a fish might seem to have an exclusive diet, they’ll often chow down on “off-menu” offerings, as wellCarnivorous fish eat meat, herbivorous fish eat algae/plants, and omnivorous fish eat both. That’s the order of things, and any fish we buy for our aquariums should fit nicely into one of these categories so we know exactly what to feed it, right? Well, if that’s the case, why on earth do my blue-chin triggers (Xanthichthys auromarginatus)—carnivores by nature—always beat my tangs and foxface to the dried algae sheets I offer and actually eat the lion’s share? After all, FishBase describes X. auromarginatus as “[forming] loose aggregations a few meters above the bottom where it feeds on zooplankton, particularly copepods.” Nowhere in this statement do you see, “Oh yeah, and it likes to tear into algae from time to time, too!”On the flipside of the coin, just as my triggers seem to enjoy ordering “off-menu,” my herbivorous yellow tang (Zebrasoma flavescens), Atlantic blue tang (Acanthurus coeruleus), and one-spot foxface (Siganus unimaculatus) will greedily gobble up any meaty items that they can fit in their mouths as well. What gives?

I was reminded of this recently when CC entrusted several of his Caribbean specimens to my care in advance of his pending move to the great state of Florida. By the way, if you “felt a great disturbance in the force” some weeks back, it had nothing to do with the destruction of Alderaan. More likely, it was just Chris’s head exploding at the thought of his prized Caribbean species intermingling with my lowly Indo-Pacific corals and fish. Did I ever mention that CC is a terrible “species-ist”?Anyway, among this adopted assortment are several color varieties of Ricordea florida. Now, prior to receiving these specimens, it had been a long time since I’d given much thought to rics, and I’d forgotten how truly stunning these humble corallimorphs can be, so it was really nice to get reacquainted with them. They’re also fairly rugged, so whether you’re a beginner, intermediate, or advanced hobbyist, R
