Ultra Cynarina

Cynarina is a genus of stony coral in the family Lobophylliidae. It is a monotypic species which means that the only species in the genus is Cynarina lacrymalis. Sometimes reaching up to 6” for a single polyp, these corals are very fleshy in appearance and often referred to as the Cat’s Eye, Tooth Coral, Doughnut Coral or Meat Coral.  The coral is found in the Western Indo-Pacific Ocean and ranges in many different color forms from pastel to vivid and translucent.  The coloration in the Cynarina coral pictured above is both beautiful and very unusual and therefore classified as an “Ultra” coral.  This coral was just featured in a newsletter from livestock wholesaler, Eye Catching Corals.

What are the Odds of Being Attacked by a Shark?

Let’s face it, anyone that has ever stepped foot in the ocean has had that moment where something unexpected touched your body beneath the water resulting in a “you tube” worthy series of epic jumps and arm flailing that put the best ninjas to shame. Most of the time, it’s just a piece of sea weed or an annoying relative, but have you ever really thought about the odds of a shark attack? Well fear no longer! Statistically you are more likely to die from fireworks (1 in 340,733) or from accidental poisoning (1 in 19,456) than a shark attack. Worldwide, there are 70 – 100 shark attacks a year, with only 5 – 15 of those resulting in death. Most of the time, if there is an incident,

Reef Life Support Systems WavePuck

Daniel Nguyen and the guys at Reef Life Support Systems (RLSS) have been working on an exciting new wave maker device known as the WavePuck.  Slightly smaller than a hockey puck, this is the 1st public viewing of the 3D printed prototype.  I first had a sneak peak at the device this past September at MACNA in Washington, DC  but until now I had to keep this information under lockdown until now. Daniel, the owner of RLSS in Canada, has developed a low profile magnetic pivotal wavemaker. At a nominal 1.5″ thick x 3″ footprint, it is now the lowest profile wavemaker device of its kind. Today RLSS announced plans to produce 4 models of the Wave Puck with the 1st model generating a maximum flow rate

The Trials & Tribulations of a Young Reef Tank

Starting and maintaining a successful reef tank is not an easy task, even for veterans of the hobby. There are many curveballs out there capable of bringing a reef keeper to their knees that can cause them to “cry uncle”, especially during the early part of a tank’s life. For my latest tank I encountered a few bumps in the road, forcing me to endure what I would term a rough start. Now mind you, I have been in the hobby for over 20 years so the knowledge I accrued has certainly made it easier for me to steer clear of past problems. For instance, in an old tank I had a wicked type of invasive algae that hitchhiked in on some live rock, forcing me to shut
