Red Seadragon Is Spectacular New Species

A paper in the Royal Society Open Science has announced the discovery of a new species of seadragon. The Ruby Seadragon (Phyllopteryx dewysea) is named for its incredible bright-red coloring and was first noticed after a male was caught during a biodiversity trawling survey in 2007. At first, scientists thought it was a weedy seadragon, but DNA analysis revealed it to be a completely new species. In addition to DNA research, the team also took a CT scan of one of the specimens. “[The] scan gave us 5,000 X-ray slices that we were able to assemble into a rotating 3-D model of the new seadragon,” said lead author Josefin Stiller. “We could then see several features of the skeleton that were distinct from the other two species, corroborating the genetic evidence.” The scientists believe the new seadragon has gone un-noticed for so long because it is found in deeper waters off the coast. The deeper water habitat may also explain its darker, red color

EcoTech VorTech ‘QuietDrive’ Pumps Announced

Rumour and speculation have been rife over the last couple of weeks but now the embargo has finally been lifted, we can stop ‘keeping it quiet’ as it were, and bring you official details on the latest product development from our sponsor Ecotech Marine! We’ve studied the offical 16 page release at length so here are the key points. Building on the already award-winning VorTech pump line, the new MP10wQD, MP40wQD and MP60wQD offer claimed improvements in noise reduction, efficiency, flow and durability. Specifically, this next evolution of the VorTech range offers up to 90% noise reduction and up to 40% more output* while the line retains connectivity and offers a new gyre flow mode.

Video: A Leisurely Look At One Of Our Fave Fishes

[embedded content] We’ve been pretty busy recently with a whole stack of product reviews but it was nice to grab a few minutes to process some of the HFR footage we’ve managed to capture in the odd spare minute. Filmed at 50fps, this particular clip is slowed down to 25fps and can be viewed at 1080p also. Resting in its favourite perch in a colony of Blue Montipora, our resident Flame Hawkfish is the perfect model for this kind of footage!

OATA Petition Needs Your Support!

Calling all UK hobbyists! OATA have recently launched a campaign to defend the UK ornamental trade and hobby from a host of overzealous campaign groups who are seeking to bring an end to the practice of keeping fish in captivity by introducing bans on the importation and sale of wild-caught and exotic species. Clearly the ramifications of such a ban would be huge – not just stopping us from enjoying the beauty of such life in our own homes, but also destroying a myriad of businesses across the country, and even beyond these shores. We strongly recommend you visit the site by clicking HERE and show your support as we have.

Problem Starfish ‘Smell The Fear’

Thought to be responsible for 40 per cent of coral cover loss in the past 30 years, the Crown-of-Thorns Starfish is without a doubt one of the main threats facing the Great Barrier Reef. But now scientists may have discovered a new way to repel them using the scent of their natural nemesis, the Triton Sea Snail. With one whiff enough to send the starfish running (or should that be crawling?) for its life, University of the Sunshine Coast senior lecturer Scott Cummins explains the Triton Snail is one of its most feared natural predators. “We put [the snail] next to the crown-of-thorns starfish and they reacted quite obviously,” he said. “They started to run away, which is quite an important finding because it tells us they do have very poor eyesight, they are sensing or smelling their main predator.” All that remains is for the team to successfully isolate and synthesise the molecule and then Cummins says this sort of repellent could be used to push the starfish off the reef and into areas where they could be destroyed. “We want to narrow it down to exactly what the molecule is then hopefully we can take that and put it into some slow release system on the reef.” More HERE

Patter of Tiny Tentacles Heard at Mote Aquarium, Florida

Credit Mote Marine LabHaving already hit the spotlight earlier this year, the Caribbean Pygmy Octopuses of the Mote Aquarium in Florida are in the limelight again – but this time they aren’t the babies, rather they’ve gone on to become proud parents. Previously shown in an image dubbed one of the “most amazing science and technology images of the year”, the aquariums Octopus mercatoris are nocturnal and secretive in the wild, and experts at blending into the reefs and rocky outcroppings they inhabit. As such, it’s perhaps no surprise that the 20 new babies from the one mated pair are currently hiding behind the scenes, too delicate and secretive to be on exhibit.

Unboxed: AquaIllumination (AI) Hydra 26

As one of the leading suppliers of LED lighting solutions for aquaria, AI have built a fantastic reputation for both quality and innovation and can call an army of reef-keepers committed ‘converts’ to their products. It is their proficiency in this innovation which particularly draws our attention to their latest offering, the Hydra 26, which packs one almighty LED punch into the smallest of packages. In this unboxing review we take a preliminary look at the unit before we install it on our test system in the near future for a full operational review. So, first things first, yes this is a small unit.

Review: AquaMedic EcoRunner 6000

The ‘beating heart’ of numerous designs, a return pump is without doubt a key component of many modern reef systems. It can be a fairly thankless task though and, due the fact that this kind of kit is often out of sight, it can be tempting to try to save money and skip the research when it comes to selection. However, when we expect such an item to perform flawlessly 24/7 with little intervention, it seems crazy to even consider cutting costs. Also, given the fact that a pump is a constant energy drain, it makes sense to look for an efficient unit that won’t make our energy metre spin like a fruit machine! For this review we take a look at AquaMedic’s EcoRunner 6000 which is part of a range that promises energy-saving, silent operation with high efficiency and long-term maintenance free design… just the ticket… or is it?! Launched back in 2012, and with 5 models spanning 2700 to 12000lph output, this range has a pump for most applications (actually certain models are fitted with needle-wheels and used in AquaMedic’s aCone skimmers). Taking the mid-range 6000 unit ‘for a spin’, the first thing that strikes us about the pump is its rugged design. Incorporating a small handle to facilitate retrieval during maintenance, this pump is very solid indeed. It took some effort to disassemble for our product shots actually, such was the tight fit of the components. This bodes well for durability but it’s worth maybe loosening it up a little before you install it on a system. Inspecting each component in turn reinforced our conclusion that this is a precision made pump and take note that it comes with pre-filter basket and hose connections included to allow it to be used in a variety of situations… internal/external, hard or soft plumbed. This pump doesn’t have any flow adjustment but frankly we aren’t worried as such devices typically exert back pressure on the pump. It would be nice to have a few other diameter connections included though. Peel back the outer shell and at the heart of this IPX8-rated pump is an electronically controlled synchronous motor which promises to deliver high flow while consuming little electricity. Actually, this pump is slated to draw just 70watts which is less on paper than our Eheim 5000 compact (which outputs 1000 litres less per hour). Checking the EcoRunner 6000 with our plug-in metre reveals an average wattage consumption of around 80 watts though, so perhaps the UK supply means our pump is drawing more power… if so take note that the output is likely increased a little also). With a polished ceramic shaft and bearing this is a very quiet pump also and barely registers on the noise app we’ve used on our previous pump and skimmer reviews. Heat output is minimal as one would expect. Although we haven’t measured the actual flow rate from this pump we can see it is noticeable more powerful than the Eheim so frankly that’s good enough for us. Obviously head pressure is going to reduce this output – take note the maximum is 3.5m. Available online from Swell UK at a price of £175.95 (at the time of writing), this pump, and others is the range, compare well against competitors with the combination of superb build quality and efficient, quiet operation most notable.
