Aquascape to Moonlight

Yes; this is a very lovely (albeit young) aquascape. Yes; the video quality is impeccable. And yes; the Apistogramma cichlids are sweet as pie. But it's Beethoven's Moonlight Sonata that is the cherry on top.

"Red tide" and palytoxin in the home aquaria

According to a new research by the American Chemical Society, their sample of aquarium saltwater tested positive for both"red tide" (dinoflagellates) toxins and palytoxins. The team developed a method to rapidly test aquariums for these toxins.

An old lighting technology all but left for dead might get a second chance at life. MIT researchers have discovered a way to recycle an incandescent's waste energy (heat) back into visible light, with a theoretical maximum efficiency far greater than today's CFLs or LEDs.

Ascension Island to be designated as marine reserve

The holy grail resplendent angelfish (Centropyge resplendens) will soon be more unobtainable than ever before. The tiny, remote Ascension Island is about to earn protection as a marine reserve.

Ascension_Island_Location.jpg

Ascension Island is an extremely remote reef found literally in the middle of the Atlantic Ocean.   As part of the British Overseas Territory, the island is used by the Royal Air Force as well as the US Air Force.  Ascension Island, along with its sister island, St.Helena, are also home to some beautiful endemic reef life, the most famous citizen being resplendent angelfish.

In the 80s, Ascension Island fishes would occasionally trickle into the aquarium trade.  The island government soon banned the export of its sealife due to concerns about the exploitation of the tiny island's natural resources.  Now the British government has announced the southern half of the island will become a marine reserve, with the northern half a monitored tuna only fishery.  The announcement comes on the heels of other marine reserves established in the past few years including Easter Island and Palau.

Resplendent angelfish has been successfully bred in captivity by RTC Hawaii for the aquarium trade.  In 2012, RTC changed their focus to applied research instead of commercial aquaculture itself.   We are not aware if any breeding program for these angelfish is currently in operation.

Blue Asian Arowanas are (pretty) amazing

Most of us have seen photos of spectacular specimens of blazing red, bright gold, or even rainbow colored Asian Arowanas. The gaudier the color, the more prestigious and and expensive the fish. Now we are seeing more examples of blue Asian Arowanas, and they're only getting more blue as captive breeding continues.

Surprise: one organism responsible for nitrification instead of two

Surprise: one organism responsible for nitrification instead of two

Nitrospira

It could never be found until recently, in a fish tank a few floors below Radboud University’s microbiology department: one single organism able to perform the complete process of nitrification. Microbiologists used to think that two distinct groups of bacteria were responsible for the stepwise oxidation of ammonia to nitrate via nitrite.

Developing a butterflyfish repellent?

Developing a butterflyfish repellent?

Butterflies are risky (at best) around corals, so reefkeepers rarely consider these beautiful fish for their reef tanks. But what if we could develop a butterflyfish repellent? A new research suggests it's possible.

Stunning SPS + Angelfish + Butterfly Reef

The video may be over-saturated and pixelated, but the aquarium's beauty is undeniable. The owner successfully mixes SPS and LPS corals with "non-classical" reef fish like butterflyfish (Tinker's and copperband) and angelfish (regal and goldflake) into a harmonious symphony of colors.

The zooxanthellae Symbiodinium sp. is best known for its symbiotic relationship with corals and clams. For the first time, researchers have discovered zooxanthellae floating in the open ocean far away from reefs by using unicellular protozoans as their host.
