Picture of the Week, Green Hammer Coral

Stop, it’s hammer time. Cheesy throwbacks to the 80s aside, the hammer coral is a staple in many reef tanks much like MC Hammer’s song was a permanent fixture in many a Sony Walkman. Getting past all of this nostalgia, hammer corals offer the best of both worlds for corals. On one hand, they have a hard skeleton, but on the other they are adorned with flowy, fleshy tissue that draws in those seeking a little more movement in the water.

Deltec Announces Expansion of Their DC Skimmer Lineup

Deltec is making a few nice moves here in 2015, adding a trio of new skimmers to their popular SC lineup. And in similar fashion to their October 2014 release of the SC 1660, all three of these new skimmers will feature DC controllable pumps. The new skimmers will be the SC 1351, SC 1456, and the SC 2061, all internal models of course, and their addition brings the total number of Deltec’s DC skimmers up to four. Beyond the new pumps, there’s really not much that has changed. The body looks the same, as does most of the add-ons

CoralRX One Shots Are Back in Action After Re-release

After an apparent hiatus from the aquarium hobby (I say hiatus because of the “re-release” verbiage used in the promotional material), the One Shot single dose coral treatment from CoralRX is back and better than ever. These tiny little packets serve as a single dose coral dip that treats a wide variety of common issues (see the list below). And now they are in a much easier to use packet. Previously, the One Shots came in small glass vials, which weren’t always the easiest to open or the safest to handle

A Smaller Maxspect Gyre Model to Hit Shelves This February

The pump that took the aquarium world by storm in 2014 is about to get a brand new little brother. Riding on the popularity of the XF150, Maxspect is releasing a smaller XF130 that will put out approximately 2300 gallons per hour, which is just under half the water flow of the original Gyre pump. The new XF130 will also be noticeably smaller, tipping the scales at 10”L x 2.95”W x 1.57”H. This makes the smaller pump around two inches shorter in overall length and one inch shorter in height, though the width stays unchanged. This drop in size and flow rates mean the XF130 is more ideally suited for aquariums 25 to 100+ gallons. As far as the price goes, the smaller model will see a $60 drop from its bigger brother, bringing it down to $239.99

Insane Rainbow-ed Out Dr. Evil Favia at Sexy Corals

Feast your eyes on this, the holy grail of favias. This stunning piece from Sexy Corals, called the Dr. Evil Favia, has every color imagineable. We spy green, blue, orange, red, purple, and even yellow. I don’t think I’ve seen a more true rainbow coral than this.

My, How Your Colors Have Changed

We’ve all heard of corals morphing under different lighting. That piece that looks great in your buddy’s tank looks dull and washed out in yours. Or, you get that coral that does a complete 180. You see it at the store and it looks good, but once established in your aquarium, it turns into a gem. Well, we as a community do talk about coral color changes quite a bit, and we think we have found one of the most extreme examples of such an event

This Pink and Yellow Blasto is Refreshingly Different

Our blasto kick continues this weeks as we feature another knockout coral, this one from Exotic Reef Creations. This pink and yellow Blastomussa, which we found on found on Reef2Reef, meets all of the requirements to be a killer piece. It sports a vibrant yellow body with an awesome pink outer ring. To add to the vibrancy of the coral, the blasto’s mouth is neon green with green lines radiating away from the center

ORA Announces Availability of Rare Japanese Kamohara Fang Blenny

ORA has set the bar really high for 2015, and we’re just a dozen days into it. They announced on Friday via their blog that they will be shipping out their latest addition to the captive bred fish lineup, the ORA Kamohara Blenny (Meiacanthus kamoharai). This stunning fish is a Japanese endemic normally found in shallow waters off the country’s southern coasts. While it is common in the wild, it is surprisingly absent from the aquarium community here in the US, though ORA obviously hopes to change all of that. In their blog post, ORA describes the Kamohara blenny has having a tolerance or a wide range of water temperatures. is the world's leading destination for sustainable coral reef farming and the aquarium hobby. We offer a free open forum and reef related news and data to better educate aquarists and further our goals of sustainable reef management.
