How to Acclimate Your Captive Bred Invertebrates

Aquarists like to broadly divide classes of aquarium livestock into two big groups, the fishes and the invertebrates. The second group is a huge catch-all, as it includes all non-fish livestock ranging from sponges to crabs. Though invertebrates are overall more sensitive than fish to sudden environmental change, ideal acclimation procedure varies somewhat between the …

Proper Tank Acclimation for new livestock is vital!

How to Acclimate Your Captive Bred Fish

Acclimation to a new aquarium home is a particularly stressful time in the life of any kind of captive fish. Like all aquatic animals, fish are shocked by rapid changes of water temperature or chemistry. Add to this the fact that fish take on a sort of psychological stress during this time, as they might …

Oithona: A Keystone Aquarium Copepod Species

In terms of both numbers and biomass, the copepods (Subclass Copepoda) dominate the zooplankton oceanwide. These minute crustaceans are of immense value ecologically because they play a central role in the linear trophic transfer of nutrients and food energy as intermediaries between primary producers (e.g. phytoplankton) and higher animals such as fish. But it’s usually …

A Closer Look at Coral Tissue Necrosis

Whether you are a dedicated, full-time coral farmer or a moderately invested hobbyist, reef aquarium keeping is risky business. This is due partly because of the inherent delicateness of corals in general, but also because coraliculture is still a relatively young (sometimes downright experimental) undertaking. Coral disease–and disease control–remains as one of the most poorly …

Aquariums almost inevitably become more complicated over time. In the course of months of operation, the “system” can incorporate more and more components. And, the livestock collection grows. Eventually, what started as a simple fish tank can develop into an intricate mess of plumbing lines and gadgets; what started as a fish and a few …

Prepared Aquarium Foods: They’re NOT All the Same

Maintaining a saltwater aquarium–especially a really nice one–is a hell of a lot of work. And this is a workload that is added to our already impossibly busy lives. Is it really all that bad to rely heavily on the convenience of prepared foods? The answer, unfortunately, is probably. There are at least a couple …

Liquid Carbon Dosing in the Marine Aquarium

When we see the crystal-clear waters of a coral reef, some of us might think “pristine” or “pure.” A marine ecologist, however, is most likely thinking “infertile.” Like a desert. Yes, there is an undeniable abundance and diversity of life there; but that is possible only because of the incredibly efficient nutrient cycling between the …

Controlling phosphate in your Reef Tank

Controlling Phosphate in Saltwater Aquaria

To take on the responsibility of maintaining a marine aquarium is to take a crash course in water chemistry. By the time you’ve successfully navigated the nitrogen cycle, you’re already faced with new, threatening chemical imbalances. Of these, one of the most persistent (though frequently unnoticed) is excessive phosphate. Perhaps the best way to start …

Copepods: The Ocean’s Cornucopia

In 1905, an engineering mishap caused the Colorado River to flood a shallow basin over the San Andreas Fault in California. With evaporation rates that exceeded rates of inflow, the massive lake began to increase in salinity; Salton Lake was born. Soon, this artificially (and indeed accidentally) made inland sea would develop its own rich …

Damselfishes (Family Pomacentridae) like the orangetail damselfish have been heavily favored by marine aquarists ever since there was a thing called a marine aquarium. There are plenty of reasons for this lasting popularity. First and foremost, damsels are among the hardiest of saltwater aquarium fishes. They are usually brightly colored and remain quite small in …
