July 2011's Most Popular Posts

By Shane Graber - Posted Aug 08, 2011 06:00 AM
In July we learned that not all propeller pumps are equal, witnessed three nuclear power plants shut down due to jellyfish infestations, found out how important cleaner wrasses are to reef ecosystems, and saw the only known captive peppermint angelfish alive and well. Here's a look back at our most popular posts for July 2011.

Experimental Comparison of Measured Flow Output of Aquarium Propeller Pumps

Hobbyists have seen significant advancements in the range of aquarium circulation pumps available over the past decade. While all manufacturers provide a flow rate for the pumps, it is not clear what methods have been used to arrive at the numbers. Further, different manufacturers may use different methods. We have presented a standard method that we hope can be adopted by the manufacturers thus enabling a more accurate and verifiable approach. Read more...


Jellyfish shut down 3 nuclear power-plants

Jellyfish just might pose a greater security risk to nuclear power-plants than terrorists! In the span of three weeks, jellyfish have shut down three separate nuclear power stations: One in Japan, one in Scotland, and one in Israel. Read more...


Seaworthy: 700 Gallon Marine Aquarium on a Mega Yacht

When cruising the open seas on a 270 foot (82m) mega yacht with over 13,000 square feet (1,250m²) of living space, a 23' long (7m) infinity pool, and helipad, what more could you possibly want? A massive aquarium, of course! Living Color engineers and installs a 700 gallon (2,650 liter) for Oceanco's Alfa Nero. Read more...


Just how important are Cleaner Wrasses to reef ecosystems?

Answer: VERY. A recent study published in PLoS ONE concludes that when cleaner wrasses are removed from a reef, reef fishes were much smaller, much less abundant, and much less diverse. If their high captive mortality rates weren't reason enough to dissuade aquarists from purchasing cleaner wrasses, this study should convince everyone why they should never be collected.

'The Ghost of Cortez' Angelfish

Cortez Marine has collected an one-of-a-kind white Cortez Angelfish. The piebald coloration of this leucistic Pomacanthus zonipectus is unlike any Cortez Angelfish ever seen. Our friend, collector Steve Robinson, discusses the story behind the fabled ghost fish. Read more...


Not again! Bleach used to kill $16,000 worth of fish!

SINGAPORE - On June 20, a maid was arrested for killing her employer's fishes by pouring half a bottle of liquid bleach into his aquarium. After being reprimanded by her employer, she took her frustrations out on his 29 innocent fish. As if this news isn't sad enough, most of the mortalities appear to be endangered Asian Arowanas!

Peppermint Angelfish video

The only-known captive Peppermint Angelfish (Centropyge boylei) is alive and well, and there's video to prove it. Glassbox Design recently shared a Japanese video of this ultra rare, ultra expensive, and ultra beautiful angelfish. Read more...


Sleeping with the fishes ... literally

Looking for the ultimate tropical getaway? Consider the Conrad Maldives Rangali Island resort. Five years ago, they opened the world's first undersea, glass-enclosed restaurant. 12 diners can enjoy their meals with the company of vibrate reef life 16 feet below the waves. To celebrate their anniversary, the resort converted the restaurant into a private bedroom suite. Here are some spectacular photos of this amazing resort! Read more...

Tunze issues press release for their Turbelle Stream pumps

Tunze has issued a press release in response to the "Experimental Comparison of Measured Flow Output of Aquarium Propeller Pumps" article published today in Advanced Aquarist. A key passage of the press release reads: "At this point we conclude that the study is correct for the flow produced by the actual pump itself and we will improve the pumps in a retrofittable manner."
