Elasmobranch Enthusiasts (Part 1): Modern Husbandry – Space

elasmobranch1 300x169 Elasmobranch Enthusiasts (Part 1): Modern Husbandry – SpaceFrom the ferocious great white shark (Carcharodon carcharias) to the graceful white-spotted eagle ray (Aetobatus narinari), Elasmobranchii are a diverse group of boneless fishes that are circumglobal, inhabiting a diverse array of habitats, temperature ranges, salinity, and niches in the world’s oceans and rivers. It is no wonder that these unique creatures, while usually boasting relatively bland coloration compared to the typical teleostei reef fishes, pique the interest of pretty much every hobbyist. This group of fishes definitely has its challenges but, with proper information and species selection, can be kept fairly easily by a moderately skilled aquarist with a generous budget. The space-swim pattern continuum As with every other family of fishes, sharks have a wide range of spacial considerations by species. “Go big or go home” is a decent motto for most species. Length, width, and shape are the most important factors with all elasmobranchs, with depth being a factor only for pelagic shark species. Most hobbyists are intrigued by pelagic (open-ocean) sharks like blacktip reef sharks (Carcharhinus melanopterus) or bonnethead sharks (Sphyrna tiburo), but a typical tank will not suffice for these obligate swimmers. They prefer a kidney-bean-, figure-eight-, or at least cylinder-shaped pool or tank to do well. These sharks need large straight-aways and long corners for energy conservation More: Elasmobranch Enthusiasts (Part 1): Modern Husbandry – SpaceMore:

Primo Reef T-Slotted Aluminum Stands Make for Some Good Lookin’ Hardware

ac6bPrimo Reef Aluminum Aquarium Stand Primo Reef T Slotted Aluminum Stands Make for Some Good Lookin’ Hardware Aquariums stands are every bit as crucial to the overall process as the aquariums themselves. They provide a place to out the tank as well as store all of the other gear necessary to keep the tank functioning properly. For years, aquarists have relied on various types of wood to serve as the structure of the stand, with particle board (MDF) and plywood making up the largest portions. In more recent times, metal stands have been put into service, but these huge and heavy stands had to be built by welders and they often cost a small fortune. While these two options have generally been the only ones available, the guys at Primo Reef are looking to shake things up a bit by introducing their T-slotted aluminum stands. These metal stands are made from aluminum, a real shocker huh, but they don’t assemble like other metal stands. Instead, these stands piece together with aluminum tubing that is slotted down the middle and fastened together with nuts, bolts, and angles brackets. It’s a whole new way to look at aquarium stands, and they can be pieces together by any hobbyist with even the slightest amount of mechanical skill. As for the benefits of using these slotted aluminum stands, for one, they look pretty slick MORE: Primo Reef T-Slotted Aluminum Stands Make for Some Good Lookin’ HardwareMore:

The H2Overflow Kits a Great Way to Make Aquariums “Reef-Ready”

1efdH2Overflow The H2Overflow Kits a Great Way to Make Aquariums “Reef Ready” When it comes to reef ready aquariums, hobbyists generally have two choices. Those are to either accept the typical huge black box style internal overflows that dominates the pre-made reef ready aquariums, or to add one of a number of different custom overflows to an existing tank that wasn’t previously reef ready. For the latter option, aquarium keepers have been limited only by their imagination, but there are few pre-fabbed choices on the market short of those unreliable HOB overflows that we all know and hate. Thankfully, the crew at Custom Aquariums has a different take on the retrofit overflow design with their including this H2Overflow. This take on the overflow box uses a small surface skimming intake attached directly to PVC plumbing that runs out the back of the aquarium. The surface skimmer sits high enough in the water that it is hidden from sight by the trim of the aquarium (assuming your tank isn’t rimless), which also helps hide the water line. The H2Overflow can handle up to 1200 gallons per hour and it measures 7.25 inches long by a mere 1.75 inches wide. And to add to the versatility, the overflow can be positioned in numerous different ways, as it can rotate a full 180 degrees. To keep the trash out of your sump, and potentially out of the intake of your protein skimmer or return pump, a removable lid sits atop the H2Overflow. To prevent clogging, the teeth of the overflow are tapered so that as water levels and/ or flow rates increase, the overflow can handle more flow MORE: The H2Overflow Kits a Great Way to Make Aquariums “Reef-Ready”More:

5 Marine Aquarium Misconceptions I No Longer Espouse

aquarium misconceptions 300x169 5 Marine Aquarium Misconceptions I No Longer EspouseCasting my mind back on my early days as a marine aquarium keeper, it’s funny how some of my stances on various aspects of the hobby have, shall we say, evolved in the intervening years. Of course, these changing opinions have led to different ways of doing things—and different ways of dispensing advice. Here are just a few examples (experienced salties, see if any of these sound familiar to you): 1) Quarantine is an extravagance I used to think quarantining new specimens was more of a luxury than a necessity. Besides, despite my failure to quarantine, I somehow got lucky and managed to sneak by with no major disease problems for quite some time. Oh, what a naïve fool I was! No one could have convinced me that I was playing a game of Russian roulette and running out of empty chambers. It took (wait for it!) an outbreak of Cryptocaryon to achieve that. There’s nothing like the sight of all your prized fish dashing around the tank and scraping their bodies on the rockwork to change your mind about the importance of quarantine! 2) Live rock hitchhikers should be eradicated with extreme prejudice More: 5 Marine Aquarium Misconceptions I No Longer EspouseMore:

Vancouver Aquarium Unveils 45 Million Dollar Expansion

I began by public aquarium career at the Vancouver Aquarium where I worked as an aquarist for over 7 years. So, I am eager to see what the 58 year old Vancouver Aquarium has in store after it’s 45 million dollar renovation. As Canada’s largest and first public aquarium, it has lead the way for public aquariums. The aquarium has a notable history, including being the first aquarium in the World to capture and display an Orca. This past Friday the Aquarium unveiled the work of the expansion, including its new entrance, 360 degree wrap-around screens that vancouver Vancouver Aquarium Unveils 45 Million Dollar Expansiondisplay pictures of the Worlds’ Oceans, and a large globe that has been positioned so that visitors can see Canada more easily. Updates were made to the Clownfish Cove children’s area which include an animal rescue center and underwater tunnels.… More:

The Kole Tang: A Commendable Surgeonfish for Medium-Sized Aquariums

kole tang 300x169 The Kole Tang: A Commendable Surgeonfish for Medium Sized AquariumsKole Tang (Ctenochaetus strigosus)Among the so-called bristletooths of the genus Ctenochaetus is one of my favorite tang species and one that I highly recommend to other hobbyists with well-established, medium-sized to moderately large systems—the Kole tang (Ctenochaetus strigosus). Physical traits C. strigosus, which is also sold under the common names yellow-eye tang, gold-ring bristletooth, and several others, has an ovate, laterally compressed body. Adults are brownish overall (juveniles are more yellowish) with numerous thin, horizontal, light-blue stripes on their flanks; tiny light-blue spots on the head and throat; a neon-blue margin on the dorsal and anal fins; and a bright-gold ring around each eye. Depending on where they’re collected, some specimens may be mostly spotted instead of striped. The maximum recorded size for this species is about 7 inches. The term “bristletooth” refers to the comb-like teeth this species and its congeners use to graze and forage. In fact, loosely translated, the generic name Ctenochaetus means “comb bristle.” Feeding In nature, C. strigosus feeds largely on detritus and microalgae—hence the preference for keeping this species in well-established tanks More: The Kole Tang: A Commendable Surgeonfish for Medium-Sized AquariumsMore:
