A baby green mandarin goby

An Overview of the Mandarin Goby

There are actually two different species referred to as mandarins, each exhibiting its own beautiful color variations. There is the psychedelic mandarin (Synchiropus splendidus) which offers a tie dye appearance featuring blue, green, red, yellow and …

When to Choose Poseidon’s Feast

Back in “the day,” to acquire a seed culture of copepods, aquarists would typically have to resort to scooping a couple cups of gravel from the bottom of a fellow aquarist’s tank. In these cases, you could only hope to have nabbed a few viable pods–and not any pests (like juvenile aiptasia anemones)! If you …

Corals in a Box of Water: Creating a Natural Reef Tank

We’ve come a long, long way in advancing natural marine aquarium keeping. Those of us who started out in the 80’s with barren “aquascapes” dead coral skeletons and crushed coral bottoms might look back with amazement at how so much has changed so fast. Just recall how many developments have taken place over the last …

Copepods under high magnification

Gutloading Live Microcrustaceans

In the sense that very, very few animals specialize to eat only one thing, all animals are omnivores, and prefer live foods. For example, when herbivores graze on turf algae, they’re not just eating algae but rather the entire “epilithic algal matrix” which includes those bacteria, protists, etc. that live on the algae. Similarly, in …

Why EcoPods are the Best Live Copepod Product Ever

Earth is a planet of pods. Wherever there is water, there are amphipods, isopods, branchiopods, and so on. Pods are an integral part of pretty much every freshwater, brackish and marine ecosystem. But even among all these big players, the tiny copepod is a giant; in terms of both biomass and sheer number, copepods (subclass …

The Whole Package: Integrating AlgaeBarn’s Kits & Combos

AlgaeBarn is hardly the only aquarium hobby-centered business to produce phytoplankton and macroalgae. But we like to think that we’re pretty darn good at it–if not the best! Consider our highly-acclaimed premium live phyto blend OceanMagik in various kits or our standard-setting CleanMacro series. If it needs to be stated, algae is kind of the …

Pod vs Sock: Do Mechanical Filters Kill Copepods?

Considering that aquarium keeping is a mere nerdy pastime, it can be surprising that there are so many contentious issues amongst hobbyists. One such big “controversy” centers around the impact of mechanical filtration (especially filter socks) on zooplankton (especially copepods). Naturally, as one of the world’s largest commercial producers of copepods, we have a couple …

4 Tips for Seeding Live Copepods

We get it… Copepods aren’t always cheap. Especially if you use a clean, high-quality, high-density, expertly packaged product with as many as four copepod species at various life stages (e.g. EcoPods!). But, using top-shelf products, you do get what you pay for. That’s why making a little extra effort to get the most out of …

Phytoplankton Species and their individual Strengths

When purchasing live foods for your tank, many people simply take the shop employee’s advice when handed a jar of unidentified copepods for their reef tank. Most do not research into the different species of copepods, we just understand that they are a major element of our clean up crews and that our fish love …

How to Acclimate Your Pods

Particularly for animals that live in water, acclimating from one environment to another–even if quite similar physically and chemically–can present serious stress. Yes, “pods” (copepods, amphipods, etc.), are known to be incredibly resilient and adaptable. Indeed, the tidepool-dwelling harpacticoid copepod Tigriopus californicus is regarded as one of THE toughest of all invertebrate species. All that …

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 …

Copepoda: 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 …

Gorgonians in the Marine Aquarium

It should go without saying that the hermatypic, stony, reef-building corals will dominate most reef aquaria. Thankfully, so long as (1) key water parameters are monitored, (2) the appropriate light conditions are provided and (3) nutritious planktonic foods are present, these beautiful plant-animal symbiotic combos easily flourish even in the care of novice hobbyists. Especially …

Eliminating Detritus in the Refugium

Ever feel like no matter how much time you spend cleaning your tank, it can never really ever get clean? Detritus build-ups can be especially frustrating as they seem to come from nowhere and seriously compromise the healthy and natural appearance of an otherwise beautiful exhibit. One solution is to construct the system in such …

Copepods

Imagine for a second how food energy from grass, a primary producer, is transferred to a bluebird. The bluebirds don’t eat grass. Rather, they consume grasshoppers—which certainly do eat grass. In this way every secondary consumer obtains life-giving energy and biomass from primary producers through an intermediate, primary consumer. So it is across the ocean, …

Amphipods and/or Copepods: Can They Peacefully Coexist?

Detritus and algal films compromise the aesthetic appearance and environmental quality of any saltwater aquarium. For sure, they present some of the most serious (and frustrating) issues for an aquarist to contend with. The easiest and least expensive way to deal with these issues is through biological control. This typically involves the use of a …
