Vertical Surge Device

 Space in the coral troughs is always at a premium at the ReefGen coral farm, and we all agree that water flow is one of the most important aspects of coral care. When one of my troughs has an area of inadequate flow, such as this Acropora grow out system, it starts under-producing. I needed to build a unique surge device to provide more flow to the stagnant corner, as well as create a chaotic alternating current for the Acropora located downstream.… More:

Chengdu’s Cube Oceanarium Sets a Record

Opened on New Year’s Eve, Chengdu’s Cube Oceanarium (a public aquarium) is an beautiful, educational wonderland located in Seaside City in the JiaoLong Port. The recently completed project has been awarded not one, but two Guinness World Records – one for the world’s largest window and one for the world’s largest aquarium window. chengdu aquarium 4-reefsMore:

The More The Merrier: Increase The Peace… With Fish

In the first investigation of its kind, experts from the National Marine Aquarium, Plymouth University and the University of Exeter have assessed people’s physical and mental responses to tanks containing varying levels of fish. Their findings were recently published in the journal Environment & Behaviour. The researchers conducted their study when the UKs National Marine Aquarium refurbished one of its main exhibits – a  45ft, 550,000 litre tank – and began a phased introduction of different fish species. Assessing the mood, heart rate and blood pressure of 112 participants as fish numbers in the exhibit gradually increased, they found that found that increased biota levels were not only associated with longer spontaneous viewing of the exhibit, but also greater reductions in heart rate, greater increases in self-reported mood, and higher interest. “Fish tanks and displays are often associated with attempts at calming patients in doctors’ surgeries and dental waiting rooms,” said Deborah Cracknell, PhD Student and Lead Researcher at the National Marine Aquarium. “This study has, for the first time, provided robust evidence that ‘doses’ of exposure to underwater settings could actually have a positive impact on people’s wellbeing.” Dr Mathew White, an environmental psychologist at the University of Exeter, added: “Our findings have shown improvements for health and wellbeing in highly managed settings, providing an exciting possibility for people who aren’t able to access outdoor natural environments.

The Two-Stripe Damsel: Hardiness and Hostility in Equal Measure

Two-stripe damsel (Dascyllus reticulatus)Among the pomacentrids (damsels and clownfishes) are many species that rank exceptionally high when it comes to hardiness in aquaria (thus their once common use as tank cyclers) but also tend to mature into little hellions that can turn a peaceful community tank into an underwater war zone. The genus Dascyllus contains more than its fair share of these hardy-but-hostile damsels, including the subject of today’s profile: Dascyllus reticulatus, the two-stripe or reticulate damsel. Though not chromatically gifted, D. reticulatus is striking in appearance nonetheless. Cute and peaceful as a juvenile, the two-stripe damsel can tempt hobbyists into making an impulse purchase only to discover later on that this Indo-Pacific pomacentrid is anything but passive. That aside, it can be a good candidate for a more rough-and-tumble community. You just have to keep that territorial belligerence foremost in mind when choosing a system and tankmates

Is It Okay to Quarantine Multiple Marine Fish at Once?

Sometimes QTing multiple saltwater fish in the same tank makes sense, other times it doesn’tAs regular Saltwater Smarts visitors are well aware, “Caribbean Chris” and I are strong proponents of quarantining all newly acquired fish for at least four weeks before introducing them to a display tank. But what about keeping two or more fish in the same quarantine tank (QT) simultaneously? Is that an acceptable practice? The answer to this question, as with so many aspects of marine aquarium keeping, depends on a variety of factors. Before proceeding with multiple-specimen quarantine, ask yourself these questions:Am I doing this just to save time in stocking a new tank? When contemplating the necessarily drawn-out process of quarantining all the livestock for a new display system, it might be tempting to think, “Hmm, if I just put all the specimens into quarantine at once, I can have a lively show tank in no time!” But this ignores the fact that whether you put all the specimens into the QT or display tank simultaneously, one sick fish among them will still infect the rest.

Avoid These 5 Live Rock Aquascaping Pitfalls

Doing your aquascaping correctly from the beginning will help avoid hassles in the futureYour long-anticipated live rock shipment has finally arrived at your doorstep, and you can’t wait to get it in your tank and start watching as life emerges from those gnarly chunks. Though you’re understandably eager to forge ahead putting the rocks in place, it’s critical at this stage to give more than passing thought to how you should arrange them. Inappropriate aquascaping now can lead to major headaches—or at least less-than-satisfactory results—down the road. Here are five live rock aquascaping pitfalls you should take pains to avoid:1. Placing your rock structure atop the “shifting sands” If your system will include a substrate of any significant depth, the first layer of rocks should be placed either right on the tank bottom (or a thin cushioning layer of substrate) or atop some type of secure supportive structure (e.g., pilings constructed of PVC pipe, a framework of egg crate material, etc.). If placed directly on top of a deeper substrate, the rockwork can be easily undermined by burrowing/digging/tail-fanning fish or inverts, potentially resulting in a catastrophic rockslide. 2

Astreopora montiporina the backstory

The story of my Astreopora montiporina colony is an interesting one. If you’re not familiar with this coral don’t worry, it is not commonly known or collected; it was named as a new species in 2011. Back to my story, I purchased a colony of clove polyps four years ago and when I was making some fragments I noticed that the rock the clove polyps were growing on was not a rock but the underside of a browned out coral colony. I removed all of the clove polyps, turned the coral towards the light, and waited to see what would happen. During the following months it slowly started to recover, the color changed from brown to green. After about a year it looked like this.
