Clams – Beautiful and Talented

Giant clams (Hippopus and Tridacna species) are already known to play a part in various important ecological roles in coral reef ecosystems, but so far, many of these roles are poorly understood. Now, a team of marine ecologists from the National University of Singapore have show how clams have been doing a lot more than perhaps they have so far been given credit for. For a start, clam shells both contribute to the structure of the reef (some species produce 80 tonnes of carbonate shell material per hectare each year) and they provide a substrate for colonisation by a host of other organisms. On the inside, the fleshy mantle cavity can host a myriad of commensal and ectoparasitic organisms while clam tissues are food for a wide array of predators and scavengers. Discharges of live zooxanthellae, waste products and spawnings are also eaten by opportunistic feeders and they can even potentially counteract eutrophication via water filtering

Review: EcoTech RMS (Radion Mounting System)

Having already taken a look at EcoTechs gorgeous Radion XR15w Pro LED light in our recent unboxing review, we now turn our attention to their much-anticipated RMS (Radion Mounting System) which ties-in beautifully with the Radion Pro range and allows these lights to be elegantly suspended above even the most tricky of systems. As ever, the kit (XR15 version in our case) comes effectively packaged and all the parts are present and correct on initial inspection. After a quick skim of the simple instructions it obvious that we aren’t going to need a degree in rocket science to assemble this piece of kit, which is great. We are immediately and pleasantly surprised that some of the components here are metal, indeed the whole thing feels reassuringly heavy-duty compared to other brackets we’ve handled in the past. Somehow, the RMS still manages to look sleek and minimal though and it’s also nice to have thoughtful design features like integral cord management included. Overall the bracket also allows for a good deal of flexibility with the light able to slide back and to, or to be rotated on the X bracket (although this is primarily of use with the XR30)

‘You Are What You Eat’ So True For Filefish

For the first time scientists have discovered a fish that can chemically camouflage itself through its diet. The new research, published in the journal Proceeding of the Royal Society B, shows that the Orange-spotted Filefish Oxymonacanthus longirostris camouflages itself by not only looking, but also smelling like its food source. Feeding exclusively on SPS coral polyps, the Filefish ingest chemicals from the corals and, since the coral reefs where the Filefish live are also home to predatory species, the researchers speculated that the filefish might also be using a form of chemical camouflage. To test their theory, study leader Rohan Brooker and colleagues captured filefish near Lizard Island Research Station on the Great Barrier Reef. The team then placed the fish in large aquariums and divided them into two groups. For four weeks, the first group was provided an exclusive diet of Acropora spathulata polyps, and the second only Pocillopora damicornis (which is not part of the filefish’s normal diet).

Unboxed: Nyos Quantum 220 Protein Skimmer

Officially unveiled at Interzoo earlier this year, and available to European hobbyists for a few months now, we thought it would be great to take a closer look at this immediately eye-catching and attractive range of skimmers from Germany-based experts in ‘high level reefing’ Nyos® Aquatics. Actually, sales were so successful on the first production run, we’ve had to bide our time for a second run to take place before we could even get hold of our unit! So now it has finally arrived, let’s get it out of the box and see if it really is ‘Built to Perform’. Receiving the largest unit in the range, the Quantum 220, we are immediately struck by the cavernous volume of this futuristic-looking skimmer. Measuring approx.

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.

Video: Gabon Creates Worlds Newest Marine Sanctuary

[embedded content] Encompassing some 18,000 square miles of ocean around the central African nation of Gabon, the world’s newest marine sanctuary was announced this week. Home to more than 20 species of sharks and rays, including threatened species like great hammerhead sharks, manta rays, whale sharks, and tiger sharks, protection of the area had been a major aim of National Geographic’s Pristine Seas project, which conducted a marine survey of parts of the nation’s almost 500-mile (800-kilometer) coastline in 2012. Making the announcement on Wednesday at the opening of the 2014 IUCN World Parks Congress, which has drawn several thousand delegates from 165 countries, the President of Gabon, Ali Bongo Ondimba, said: “Today I can announce our decision to create a network of marine parks covering about 23 percent of Gabon’s territorial waters and EEZ [exclusive economic zone], within which no commercial fishing will be allowed”.
