A new Ecoxotic LED light should be available soon. Reportedly, this new 50 watt multi-chip LED light should first appear on the market in a pendant, followed by a fixture. Both freshwater (7000k) and saltwater (undecided K at this point) versions will be available. We are starting to see the spotlight trend, widely used in Japanese reef tank, begin to infiltrate the US hobbyist base more and more these days. This new LED light from Ecoxotic can brighten up any shaded spots in your tank, and provide quite a punch with it’s high PAR ratings.

We had a chance to see this light at in action over the yet to be released Ecoxotic nano tank at ReefStock. You can see just how bight this new LED light is going to be, absolutely flooding the small tank previously lit by the Ecoxotic Panorama LED Fixture.

We visited Salty Critter in Vermilion OH, this week, and wanted to show you what we saw. Salty Critter opened it’s doors and began offering saltwater fish, corals and supplies back in 2000. Along with a 4000 gallons coral system, and over a 1000 gallons in fish system, the marine reef & aquarium store also offers aquarium maintenance services, custom tanks, and setup.

From ORA corals, Australian acans and chalices, to acropora colonies, zoanthinds and ricordeas, Salty Critter always has an extensive collection of corals available. The store has recently changed its layout, in anticipation of an impending upgrade (more info below). As you walk into the store, you are confronted with an entire half of the store, dedicated to a large supply of dry goods. You can find anything from Protein Skimmers, Calcium Reactors and accessories, aquarium controllers, wavemakers, powerheads, submittable and external pumps, metal halide, T5, PC and LED lighting options, aquarium maintenance tools and much more. There is even a portion of the store dedicated to used equipment, for those of us who are looking for upgrades at a bargain. Next to the register, Salty Critter stocks various salts, dry and live sand, aquarium additives, and a wide selection of dry and frozen foods.

As you make your way to the livestock section of Salty Critter, you will first see a a wide selection of nano tanks, along with the latest cubes and treads in the aquarium industry. Naturally, the store can’t stop every tank at every size, but just go ahead and ask owner Dan Leaky, or any of the Salty Critter staff members, and they will get you a quote.

The livestock section is usually stacked; the front tank has some high-end corals, including a full selection of ORA releases, and always has a wave going, thanks to a combination of the latest powerheads and wavemakers. Both sides of the center aisle are lines with rows of 40 gallon breeders, filled with choice SPS, LPS, Palys, anemones, and a selection of reef-safe fish and invertebrates. The right aisle contains large bins full of a nice variety of liverock. The end of the livestock section includes 2 separate fish-only system, which feature some excellent choices for both reef and fish only tanks.

Alright, now let’s talk a little about what’s to come. Salty critter is in the midst of a large expansion which will include additional fish systems, as well as a new propagation section which will feature several 10’x4’x16″ tanks, visible from both sides. This new system, will allow Salty to offer and stock a larger selection of corals species and colors. Check back with us to watch this transformation.

Earlier this week we reported that ORA is preparing to release their captive-bred Mandarins. Well, we had a chance to look at them this week at the Global Pet Expo in Orlando. The ORA captive-bred mandarins looked plump and happy, swimming around the ORA reef tanks. A few photos show off the ORA Pearlberry, ORA Hawkins Blue, and a few of the newer releases like the Green Wooly and the Purple Stylophora.

Again, we would like to emphasize that the advantages of buying a captive-bred Mandarin. Being that these species will be accustomed to eating frozen food, keeping a healthy well-fed fish will be much easier, and the rate of successful rearing should increase. We will report a few more details in a soon-to-come article.

An High Output LED fixture from Marineland was on display at Global Pet Expo in Orlando. We have some confirmed information from Marineland that we wanted to share with our readers. It is important to note that the fixture seen at the Global Pet Expo was an early prototype, and there will be modifications before the final product is released. Currently, the release date is scheduled for August of 2010.

The 24″ LED fixture that was on display, featured a total of 21 1W LED’s, 18 whites and 3 blue. The white LEDs used are 5500K, but Marineland is experimenting with 10000K ones with their goal being to provide a crisp blueish-white light. This will be achieved by either altering the white LED bulbs, or using more or different blue LEDs. For example, a combination of 420nm and 460nm blue LEDs.

The shell of the new High Outpput LED fixture from Marineland will be made of aluminum. The new shell, is “beefed up”, and utilizes additional cooling vents for improved passive cooling capacity. It looks like Marineland is on the right track for developing this fixture, and we’ll keep you updated as new details are released.

Below, you will see the Marineland HO LED prototype displayed over a reef tank at the show.

The Flashing Tilefish, Hoplolatilus chlupatyi, or Chameleon Sand Tilefish has the spectacular ability to rapidly flash bright colors when stressed or frightened. The normal coloration of these fish is blue with a green dorsal ridge and a yellow stripe through each large eye. This delicate species is collected in deep water (30 meters or more) in the Philippines. Because of the difficulties of diving and collecting in deep water, Flashing Tilefish command a higher price and often suffer from improper handling and decompression issues.

When purchasing new Flashing Tilefish it is imperative to obtain specimens that are healthy and eating very well. The fish should be eating frozen mysis, brine shrimp, and other small meaty foods with gusto, but if it only picks at food, pass on it. Flashing Tilefish are susceptible to Ich and parasites, but are also very sensitive to copper medications. Quarantining new tilefish can prevent disease and condition the fish without the stress of a busy reef tank. Flashing Tilefish are sensitive to bright lighting, so be sure to acclimate the fish slowly to the lighting in a well-lit reef tank.

Flashing Tilefish are highly social and form monogamous pairs. Having a pair or group of tilefish can help them adjust to aquarium life and prepared food much more easily. Some hobbyists report that Flashing Tilefish use color changes to communicate with one another.

Flashing Tilefish are very shy and may hide constantly when added to a new aquarium until they become familiar and comfortable with their new home. Once a Flashing Tilefish adjusts to captive life, it will not change color anymore. If your Flashing Tilefish changes color, try to discover any stressors or aggressive tank mates that may be bothering it and remove them. Flashing Tilefish are also very sensitive to changes in water quality. A healthy Flashing Tilefish may hide part of the day, but should be active and swim often, especially during feeding times. The fast metabolism and high activity of these fish requires them to be fed at least twice daily.

Flashing Tilefish need a lot of swimming room and require an uncrowded aquarium of at least 55 gallons (ideally 100+ gallons) with a deep sand bed for the fish to dive into when startled. Most captive tilefish die from starvation, stress, poor handling, or jump from the aquarium. All but the most well covered aquariums can be a risk. Even a well adjusted tilefish may actively search for an escape, jumping out of the aquarium to its death.

Earlier this week, we told you about the upcoming Skimz Monzter II. While we wait, we wanted to show you what else Skimz has been up to. The Skimz TurboMagnum has been installed at a shrimp farm in Singapore. This giant skimmer is 600mm diameter (23.6″) and 2.5 meters (over 8′) tall!! The Skimz TurboMagnum is powered by a 2 16,000 l/h pumps made by a Spanish manufacturer, and incorporate a custom venturi that Skimz developed together with a 3rd party. Each one of these large skimmers is rated for 20,000 liters (~5283 gallons), and comes with a self cleaning head, similar to the Bubble King skimmer. In addition to the rotating neck cleaner, the Skimz TurboMagnum has 3 freshwater jets that clean the inside of the cup. The large skimmer body of the Skimz TurboMagnum utilizes a bubble plate, and the giant cup has a large drain pipe attached to it.

Skimz actually offers the TurboMagnum with diameters between 300 and 1000mm, and heights of 2-2.5 meters (made to the client’s specifications). Anyone want to try this bad boy on their system?

A Breeding Diamond Gobies Video was sent to us by a new member. The video begins with 100’s, if not more, of Diamond goby larvae swarming around a tank. After a few moments of showing just how many of them hatched, we are taken back 24 hours. We then see the Diamond Goby couple attending to their nest and preparing it for the upcoming event. Then begins the mad rush by the mated diamond gobies to hide and protect the nest. The next few minutes cover the hard-working goby mindfully working to disguise the home of it’s impending newlyhatched.

Oceans Reef & Aquariums (ORA®) have announced they have succeeded in commercially breeding Mandarins. The advantage of these captive bred mandarins from ORA, is that they are conditioned to eat frozen food, and therefore are much less likely to suffer from starvation. We should have photos for you from the Global Pet Expo in Orlando this coming weekend.

For many years marine aquarium hobbyists have been captivated by the exquisite beauty of Mandarin Gobies (actually Dragonettes). Their popularity, however, is tempered by the fact that they are difficult to feed in captivity and are subject to questionable collection practices in the wild. Unfortunately, most Mandarins succumb to starvation in home aquariums, even with the best intentions and attempts at feeding. Thankfully, all of that is about to change.
ORA biologists have succeeded in developing the methods needed to breed and raise commercial numbers of the two species of Mandarins, the Blue Mandarin (Synchiropus splendidus) and the Spotted Mandarin (Synchiropus picturatus). Building on the early success of breeders such as Julian Sprung, Wolfgang Mai, and more recently Matt Wittenrich, ORA is now poised to have commercially bred Mandarins available to everyone. The significance of this cannot be understated as it is a major advance in marine aquaculture and solves many of the problems associated with keeping these species.

Just as the first captive bred Seahorses were trained to eat frozen foods, ORA has already trained our baby Mandarins to eat commercially available frozen diets. This fact alone makes them easy to feed and care for, and the average aquarist will delight in not having to worry about sources of live food for their finicky eaters. Our goal is to have them soon weaned onto a pellet diet. We expect to have these fish eating pelletized foods before being released for sale.

ORA is the leader in bringing the marine aquarium industry new and exciting aquacultured species. With the addition of Mandarins to our ever-growing list, a major milestone in aquaculture has been achieved. We are sure that our retail customers and hobbyists alike will be elated that captive raised Mandarins are finally available and that a page has been turned in the tragic history of this beloved aquarium fish.

We expect to have significant numbers of Spotted Mandarins available this summer. Blue and Red Mandarins will be available in more limited quantities around the same time.

A robotic fish was on display at FC Expo 2010. A team from Osaka City University exhibited a small fish, who’s swimming is powered by a cylindrical solid polymer fuel cell called PowerTube. The 100mm-long robotic fish is driven by a magnetic actuator and can rise and dive by changing it’s syncro device center of gravity. This gives this robotic fish a swimming style that closely matches real fish.

Powered by a lithium polymer battery, this robotic fish was first designed to use a motor, an approach that proved to consume too much power. Next, the designers though of using a neodymium magnet inside of a coil, and then passing a current through it. This made the magnet move from side to side, and therefore propel the fish forward. Utilizing this method, they were able to reduce the power draw to just 10 milliwatts!! In the future, more complicated motions can be programmed to mimic different swimming styles.

Researcher think this may allow them to more closely study schools of fish in the wild, as the fish are less likely to fear a machine that resembles them, then a “clunky-looking machine”.

Alright, let’s wraps these little guys in some silicone, and toss them in our tank. Let’s make the first one a Gem Tang!

fan shrimp goby

The Fan Shrimp Goby, Tomiyamichthys latruncularius, formerly known as Eilatia latruncularia, is a little known goby from the Red Sea and the Maldives that is rarely seen in the aquarium trade. This beautiful goby is white with a mottled, iridescent copper and gold pattern. The dorsal fin is tall and rounded and has a dark brown blotch between the fourth and fifth dorsal spine. The males can be identified by filaments on the dorsal fin. It is often confused with its close sub-tropical relative the Monster Shrimp Goby or Mottled Shrimp Goby, Tomiyamichthys oni, which is found only in southern Japan and can be distinguished by a dark line running through each eye.

In the wild Fan Shrimp Gobies are found living in pairs and form a mutual symbiotic relationship with Alpheus randalli, the Candy Snapping Shrimp or Red Banded Snapping Shrimp, but may pair with the Tiger Snapping Shrimp, Alpheus bellullus, in captivity. A Fan Shrimp Goby does not require a snapping shrimp in captivity, but is never found without one (or a pair) in nature. The snapping shrimp provides shelter for the goby and itself by digging elaborate burrows in the substrate while the goby hovers nearby, watching for predators. The snapping shrimp has poor eyesight and keeps an antennae on the goby at all times, ready to dart into the burrow if the goby signals danger by quickly flicking its tail. Every evening the gobies and snapping shrimps retire to their burrow, and the shrimp seals off the exits. In the morning the gobies will emerge from the burrow and stand guard while the shrimp maintains the burrow; afterward they will forage for food.

The Fan Shrimp Goby should be housed in an aquarium of at least 30 gallons with only small, peaceful tank mates. A deep mixed-grade sand bed with plenty of rubble and crushed coral will be needed for the shrimp to build its burrow. The Fan Shrimp Goby is very shy and may hide for the first few weeks after being added to the aquarium. Frozen Mysis, brine shrimp, pellets, and most other foods are usually accepted by Fan Shrimp Gobies. The Fan Shrimp Goby is peaceful and may be kept with other shrimp-goby pairs as long as ample burrowing room is provided for each shrimp-goby pair.
