Heartbreaking Goldfish Funeral

 Think back to when your most favorite fish died….or does it hurt too much? Some of us get very attached to our little fishy friends and may even secretly shed a tear or two when they pass. So I think we can all commiserate with this little boy who lost “Top” to the golden throne. When my Black Ice Clown fish committed suicide by jumping out of his very comfortable Fluval M90 tank, I felt a sinking feeling in my stomach. Watch the video, but make sure you have tissues nearby and your fish are doing well.  MORE

Mischief Reef

china Mischief Reef was discovered by Henry Spratly in 1971. It is rumored to contain vast amounts of gas and oil. Geographically the area sits 105 nautical miles from the Philippines. Since the late 1900’s it has been a source of tension in Asia as claimed territory. However, since January, China has been dredging sand from around Mischief Reef and using up land mass hundreds of miles from China’s shore. The location has been an area of contention between China, the Philippines, Vietnam and Taiwan. Shacks on stilts have quickly been replaced with bulldozers and machinery. MORE

Lighted Surfboard Shark Deterrent Being Tested

Surfboard-Experiment-Olivia-Looking-UpIt’s not surprising that surfers in Australia are more concerned about being attacked by sharks. Seals are prey for sharks. Surfers in wet suits floating atop of surf boards can pretty closely resemble seals. Researchers in Australia are testing this theory. Researchers have been recording activity of seals at Sydney’s Taronga zoo and then comparing that to videos and sound recordings of swimmers and people paddling surfboards in the same tank. “What we are trying to do is understand what the shark is interested in and what their natural prey’s signals are, to see if there’s anything to this myth that they mistake surfers for prey,” Hart said.  MORE

Marine Aquarium Terminology: “Nutrient Export” Defined

Protein skimmers do a great job of exporting dissolved organic compounds, which bond with air bubbles in the reaction chamberAmong the myriad mysterious terms that might give neophyte marine aquarists a migraine (okay, I’ll stop with the gratuitous alliteration now) is “nutrient export.” What does this term mean? Is it just a fancy way of saying “filtration”? Well, not exactly, though certain forms of filtration do play a part. For our purposes, nutrient export can be defined as the elimination of substances that (directly or upon decomposition) degrade water quality and fuel the growth of undesirable algae in marine aquarium systems. So, let’s take a look at some of the common methods we rely on for nutrient export, including some that only do the job partway:Mechanical filtration First and foremost, it’s important to understand that mechanical filtration—the straining of particulate matter from the water—is not, in and of itself, a form of nutrient export. Uneaten food, fish poop, and other detritus trapped in a mechanical-filtration medium (e.g., floss, sponge, or a sock) with water flowing through it will continue to break down and release dissolved nutrients into the system. It’s not until the hobbyist rinses or replaces the medium that the nutrients are actually exported. Water changes Provided your makeup water isn’t nutrient-rich (which it shouldn’t be if it’s processed through an RO/DI unit or otherwise purified), water changes are the most reliable method of nutrient export MORE

Write-Up Wednesday: Coralline algae

 Coralline algae is a red algae and the pink or purple form is more common in saltwater aquariums. In the ocean coralline algae is found on nearly every reef and in the wild several unique forms exist such as types that grow in a scroll pattern, a branching pattern and a lobed pattern. In saltwater aquariums nearly all coralline algae is of the encrusting type. Coralline algae uptakes calcium during growth and for this reason you may need to increase calcium doses if you have an abundance of coralline algae in your tank. Magnesium is also though to boost it’s growth. Products that claim to encourage coralline algae growth are usually nothing more than concentrated doses calcium and magnesium so simply raising your tank’s calcium and magnesium levels will likely get you the same result assuming there is some amount of coralline algae in your tank. If you don’t see any coralline algae in your tank, acquiring scrapings or a frag with some coralline algae on the plug will introduce the algae into your system.
