A 2012 scientific study confirmed what many reefkeepers knew: Vermetid snails impede stony coral growth and sometimes outright kill them. A new study finds that these gastropods harm reefs in another way. They also drastically reduce algae grazing by fish.
How about a blind fish that still has the gene responsible for perceiving light? How about a fish that broods its eggs in its gills?! Not weird enough? Then how about one with an anus located right behind its head?!! Combine all these attributes and you have Amblyopsis hoosieri, a newly discovered cave fish from Indiana.
Reef corals and their symbiotic algae live together and are dependent on one another for survival. However, a new PSU study finds that they evolved independently, providing new insight into how corals might cope with warming oceans.
With a little ingenuity and a big helping hand from atmospheric pressure, you can create a water "watch tower" that appears to defy gravity. Koi seem to love it. Physics rocks!

- Make an acrylic tank.
- Turn it upside down.
- Attach to pond with bottom of the tank below the water line.
- Vacuum out the air. Water fills the box.
- Enjoy confusing, entertaining, and empowering your pond fish.
In part II of the Ultimate Reef Tank Lighting Series we visit Mike Paletta 4 months after the initial installation of the new lighting system. The goal of this project remains the same, find the perfect man-made optimized light source for coral growth and coloration.
A big allure of planted and reef aquariums is the art and science of aquascaping our glass boxes. But what if you had a nearly unlimited canvas? The non-profit organization Coral Guardian partners with Oceanscape to restore wild coral reefs through imaginative and inspiring reefscaping.
The Madagascar Clownfish is one of the rarest Amphiprion spp. both in captivity and in the wild, so it is with great excitement we document what may be the first captive spawning event of A.latifasciatus.
A new research proves just how important captured food is for photosynthetic reef-building coral (at least Pocillopora). Juvenile specimens exhibited almost cubic increases in growth and survival when they were fed Artemia salina regularly for 24 weeks prior to transplantation.
An electronic tag of a 3 meter great white shark washed ashore. The data it gathered is the stuff of nightmares, showing the shark had rapidly plummeted to a depth of 580 meters (nearly 2000 feet)! At that depth, the temperature sensor jumped from 46 degrees to 78 degress F where it remained for eight days at varying depth before returning back to sea temperature. Something had dragged the apex predator (or at least the sensor) down to the abyss ... and ate it!
Symbiotechs, a company "specialized in the sustainable sourcing and innovative screening methods for faster drugs discoveries from corals," and the non-profit reef conservation organization Coral Guardian are seeking crowd-source funding to study TGFB-Beta molecules in corals.
After Giesemann announced their new PowerChrome T5 bulbs, there has been some confusion regarding the status of the pre-2014 T5 PowerChromes. D-D, the creator of Giesemann's former PowerChromes, wants aquarists to know that while their partnership with Giesemann has ended, D-D's popular T5 bulbs are still available and should not be regarded as "last gen" technology.
The Catalina Goby, Lythrypnus dalli. This species changes its sex and behaviors, but not its coloration.
We welcome Ross DeAngelis to our writing team. Ross is currently researching clownfish behavior at the University of Illinois and has recently worked with cichlids at the University of Texas. In the first article of his multi-part blog series, Ross describes the interesting social systems and related sex changes amongst fish.
Only instead of couch cushions, we're talking about a reef in the Lower Antilles. And instead of money, we're talking about a relatively rare Caribbean Acropora, A. prolifera. Scientists discovered an unexpected, new, large and healthy A.prolifera reef that wasn't there in 2011.
These two recently uploaded videos show us the clear contrast between "old school" reefkeeping versus "leading edge" reefkeeping. It also shows us that (as with nature) there is more than one definition of beauty. Different strokes for different folks. Which aquarium is more to your liking?
Here is an "old school" soft coral aquascape featuring earth-tone brown color palette and full spectrum lights. This type of aquarium ruled the scene in the late 80s to early 90s.
And here is a "new school" stoney-dominated aquascape featuring brilliantly pastel "ultra-low-nutrient-system" coloration and blue lights. This type of exhibit dominates our hobby today.
Our friends at 3reef.com have been down for the past week gearing up for a major site upgrade. They're now back online with a completely new and modernized website. Their hard work definitely paid off.
