It started so innocently ...

It started so innocently ...

What's that carpet anemone doing in there?

Is there anything more elegant and enchanting than the gentle sway and intoxicating pulsation of xenia corals? If you find their lure irresistible, you might want to read this reef2reef thread titled "So, you think you want to keep Xenia..."

Diving the fluorescent reef [video]

Night diving a reef is a treat, especially if you are using a high intensity LED light that emits spectra between 450-470nm like the unit FiveDiveGear manufacturers for marine biologists and marine explorers.

The lighting that FiveDiveGear manufacturers makes the marine world come alive with fluorescence during night dives. Colors that you would not see during the day jump out at you as you explore the night reef. Take a look at the video below and their Youtube channel for great examples of what these 6 watt units can do.

What is fluorescence?


Adam Blundell, M.S. writes about 'The Seen and Unseen World of Coral Fluorescence' in Advanced Aquarist's June, 2005 issue:

Fluorescence is a process whereby a matter of energy is absorbed by a substance, and then released by that substance with less energy. In this case a light source of high energy (lets say blue light) is absorbed by a substance (a coral) and then released with less energy (i.e. green light or red light).

Dana Riddle writes what may be the most comprehensive series of articles on coral coloration & fluorescence:

Body lotions made from aquarium-grown soft corals

Scientists have developed a skin care product line using chemicals extracted from captive grown soft corals. The extract contains an anti-inflammatory compound that is said to cure small wounds and (like most lotions marketed today) slow the skin's aging process.

French SPS reef is about as packed as an aquarium can get

Thoughtful, modern (these days, that means minimalistic) aquascaping isn't required when your tank is completely - and we mean completely - filled with stony corals. Check out this outrageously lush reef aquarium from France. Sure, it's a featureless "fruit stand" aquascape, but we dare anyone to argue it doesn't bear glorious fruit.

Friendly tips: Watch the video in HD if your connection allows it.  There is also no redeeming quality to the audio, so we suggest you mute the sound.

Probiotics significantly increase growth and health of larval clownfish

Probiotics significantly increase growth and health of larval clownfish

Probiotics significantly decrease the metamorphosis time for larval clownfish. Left: treated with probiotics. Right: not treated with probiotics.

Probiotic organisms are live microorganisms that are proposed to have health benefits to a host organism. In the case of this clownfish study, researchers tested the effects of a lactic acid bacteria on newly hatched clownfish larvae. The results were surprising!

We've all seen pictures of reef fish with large parasitic isopod clinging on them. It's not a pretty picture, and it turns out reef fish are doubly (and negatively) affected by having to carry around their unwanted hitchhiker.
