Good morning friends, sorry about not posting yesterday but I got busy and then just ran out of time. I have a fun blue-light photo for you all today with Aimee as the star all decked out in her new Ikelite yellow glasses and her camera completely decked out in Ikelite blue-light fluorescent gear! So for those of you non-divers trying hard to figure out what is going on here let me try to better explain. What we are doing is putting blue-filters over our normal white light flashes, putting a yellow filter over the lens, wearing yellow glasses over our masks and using the white light VEGA’S (Ikelite video lights) as our main search lights, which also have blue filters screwed onto them.
Good morning friends, I have a pair of Honeycomb Cowfish, Acanthostracion polygonia for you all today that I photographed just moments before sunset. Every day here on the Caribbean reef around dusk many species of fish set out to find a mate and spawn before sunset, it’s by far the best time to be out with a camera. These unique looking box shaped Cowfish usually spend the day by them selves but around dusk will set out to find a mate. Once found the Male (in front) usually starts the courtship ritual by bumping into the female, swimming fast circles around her and showing off his beautiful electric colors which they can change in the blink of an eye! These fish are fairly uncommon to see and I have never found a baby one, it’s on our top 10 hardest fish to find list
Following on from our recent unboxing review, we’ve now had chance to install our XR15w over the test tank, hook it up to one of EcoTech’s ReefLink wireless controllers and have a good old play with the various settings and functions on offer. In this review we’ll detail exactly how we’ve integrated it onto the test tank, and evaluate the units capabilities in a real hobbyist setting. So the first thing we needed to do with our unit was to mount it, and to achieve this we decided to use a custom-cut sheet of glass to support it from underneath. Although any of the EcoTech mounting systems would have been fine for our tank, the other light we are currently testing (an AI Hydra 26) wouldn’t fit with this system so we needed something universal.
Following on from our recent unboxing review in which we covered the basics of this unit, we’ve now had the XF150 running on our test tank for a few weeks so we thought we’d share out observations of this product in a full operational review. We’ve also been monitoring discussions on various forums with interest and we’ll aim to specifically discus some of the points raised with our own direct experience. Firstly, the XF150 is easy to install but it’s worth familiarising yourself fully with the operation of the device before sticking it straight in the tank. Although the unit comes in a single piece you will need to reassemble it if you are wanting to use it for anything other than constant one way gyre generation as the different rotors and cages will need to be fitted. It’s certainly worth running through this process anyway actually as being familiar with the principle behind the equipment’s operation will likely mean you get more out of it
So the holidays are finally here and at last we’ve got a bit of time to spend tinkering with the test system. Hopefully the short break will allow us to get to all those jobs we’ve put on the back burner while we got on with the everyday grind! It’s also a good time to stop and reflect a little on how things are going, indeed in the words of Ferris Bueller, “Life moves pretty fast. If you don’t stop and look around once in a while, you could miss it”.
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

Good morning friends, this is for those of you just sitting around wondering what is the largest sponge species in the Caribbean. Well, it’s the beautiful “Giant Barrel sponge”, Xestospongia muta and no two are alike. I found this glowing red giant on wednesday at 90 feet east of the Substation and it stands about five feet tall, pretty incredible!! During the day the sponges are home to crabs and shrimps, and all kinds of fish swim in and out of them, they are truly one of my favorite sea creatures!
