X. auromarginatus: A Well-Mannered, Reef-Friendly Triggerfish

gilded triggerfish 300x169 X. auromarginatus: A Well Mannered, Reef Friendly TriggerfishMale Blue Throat Triggerfish (Xanthichthys auromarginatus)As I alluded in an earlier post about the Niger triggerfish (Odonus niger), triggers in general aren’t usually among the first species that come to mind when one is seeking an aquarium specimen with a peaceful disposition. Certainly as far as reef-friendliness is concerned, most of us would probably put triggers as a group somewhere pretty close to the bottom of the list of suitable fishes. While that viewpoint may be justified in many cases, some triggers are relatively inoffensive toward sessile invertebrates and actually make decent candidates for suitably sized reef systems. Among these is Xanthichthys auromarginatus, the bluechin trigger (a.k.a. the blue-throat trigger or gilded trigger) from the Indo-Pacific. Physical traits Typical of triggerfishes, X. auromarginatus is highly laterally compressed (flattened from side to side). This species exhibits sexually dichromatism, meaning there are distinct color differences between the genders. Both sexes are light brown to gray in overall coloration with a myriad of tiny light-blue dots lining their flanks. The males are easy to distinguish from the females by the presence of a distinct blue patch on the chin and the bright yellow margins of their dorsal, anal, and caudal fins.

The Beautiful, Beginner-Friendly Bubble Coral

bubble coral1 300x169 The Beautiful, Beginner Friendly Bubble CoralRecently, I found myself musing over the livestock lineup I had in my first reef tank many years ago. Along with a variety of easy-to-keep soft corals and a handful of hardy fish, I fondly recalled that I also had a solitary large-polyp stony (LPS) coral that brought me a lot of enjoyment—a bubble coral, known taxonomically as Plerogyra sinuosa. For as delicate as this coral looked, and its common name sounded, it proved to be quite a rugged and durable specimen. In my opinion, this wonderfully unusual-looking species is well worth keeping for beginners and experienced reefkeepers alike. I should note that there are other so-called bubble corals in the Plerogyra and Physogyra genera, but Plerogyra sinuosa is the species you’re most likely to come across and the care requirements for each are pretty much the same. Physical traits P. sinuosa comes by its common name honestly, as its tentacles are modified into oval-shaped, bubble-like vesicles, which, depending on the specimen, might be white, tan, green, yellow, or even bluish in color. If you look closely at some specimens, you might also notice interesting fingerprint-like striations or shiny bands on the vesicles. The bubbles remain expanded during the day but contract at night to reveal tapered feeding tentacles. Also after lights out, P More: The Beautiful, Beginner-Friendly Bubble CoralMore:

The Polyp Craze, a Look at Why Zoanthids and Palythoas are So Popular Even After All These Years

29f9reefkoi14 1024x833 The Polyp Craze, a Look at Why Zoanthids and Palythoas are So Popular Even After All These Years
In this hobby we see coral and invert phases come and go. From clams to chalices and even maxi mini anemones, it seems like they all go through a lot of initial hype then slowly decline in popularity. One of the mainstays in the hobby have been zoanthids and palythoas, which have been the craze for quite a while now. They have been in demand for what seems like an eternity and they do not appear to be getting less popular. Instead, it seems like they’re constantly on the rise. Zoas and palys are highly favored in the hobby by both beginner and expert reefers alike. They don’t require much in terms of care like other specimens and they grow under many types of lighting from T5s to LEDs. Polyps grow at the bottom of the sand bed or on your highest rock. They don’t necessarily need to be target fed like other corals and they also do not require us to dose things like calcium.

Stunning High Res Photos of Segrest Farms’ Aberrant Moorish Idol

5fe8Segrest Farms Aberrant Moorish Idol 4 Stunning High Res Photos of Segrest Farms’ Aberrant Moorish Idol
Yesterday, we broke news on the amazing aberrant moorish idol that popped up in the holding tanks of Segrest Farms. Unfortunately, the images in that post were not the best quality, but Segrest delivered the goods today with a fresh batch of high res photos showing the amazing moorish idol in all its splendor. They just uploaded them to their Facebook page moments ago, and the images confirm, at least in our humble opinions, that the fish is a moorish idol and not the proposed hybrid that many folks were chattering about on social media sites. That said, this is the most unique moorish idol we’ve ever laid eyes on. This aberrant form has significant yellow markings all over its body, with only slight hints of the black bars that are normally seen. It’s such an amazing fish and we’re grateful to Segrest Farms for keeping us in the loop in a big way. Continue below for a rather impressive gallery. <! #gallery-1 margin: auto; #gallery-1 .gallery-item float: left; margin-top: 10px; text-align: center; width: 33%; #gallery-1 img border: 2px solid #cfcfcf; #gallery-1 .gallery-caption margin-left: 0; ]> MORE: Stunning High Res Photos of Segrest Farms’ Aberrant Moorish IdolMore:
