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."
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.
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 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.
Green corals can be both beautiful and fascinating, but their overabundance in the aquarium hobby has led many reef tanks to be dominated by a single color. By avoiding various shades of a single coral color and understanding how corals grow and interact with each other in the aquarium, hobbyists can prevent their tanks from becoming an eye-sore.
Asbestopluma hypogea is to sponges what the Venus Fly Trap is to plants. Unlike the vast majority of sponges that filter feed, this rare carnivorous poriferan captures small crustaceans using filaments covered with hook-like spicules ... like velcro! The recent discovery of this rare species in the Mediterranean has prompted conservation measures.
Coral reefs celebrate life with dazzling displays. Here is the eighth installment of our HD wallpapers. James Wiseman (www.reefpix.org) brilliantly frames a breathtaking reefscape filled with colors and shapes more spectacular than any pyrotechnics.
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.
On April 1, 2011, Ecotech introduced their new Coral Glue to the market: A triple distilled, super strong, quick-setting cyanoacrylate gel sold in a squeeze bottle with an ingenious non-clog tip. The glue was initially only available in a large 295ml bottle. Ecotech is now offering their Coral glue in a smaller 75ml bottle.
The Coral Beauty deserves its reputation as one of the best and easiest to keep Dwarf Angels, it is so often seen as THE Dwarf Angel of choice, passed over perhaps only by the slightly more expensive Flame Angel.
The Harlequin Filefish (Oxymonacanthus longirostris) is not a commonly kept reef fish because it is a corallivore with a diet consisting mainly of Acropora polyps. But have you ever wondered why this unique species is colored and shaped the way it is? And what's with the oversized first dorsal fin?
Anyone want to win some free reefkeeping prizes? I thought so! Marine Depot is running a new giveaway. Subscribe to their email newsletter for a chance to win one of three advanced cooling fans. It's that simple!
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.
Modern science sheds new light on corals; Australian scientists have completed the first total genome sequence of Acropora millepora - an iconic, fast-growing coral popular with SPS fans. The research will pave the way to better understandings of how stoney corals function on a molecular level.
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. Collector Steve Robinson, discusses the story behind the fabled ghost fish.
