Copepods

  • Amphipods Are Not Copepods

    There is hardly a more natural way to feed your aquarium animals, or to clean your tank, than with microcrustaceans. It's pretty safe to say that these little creatures, frequently referred to as "pods," have indeed revolutionized saltwater aquarium keeping. That's not to say that hobbyists didn'...
  • Are Copepods a Good Sign?

    Copepods are widely believed to constitute over 75% of the biomass of all zooplankton on Earth. They may be found in nearly every marine and freshwater habitat from coral reefs to roadside ditches. But it is not just their omnipresence that makes them so important ecologically; because these tiny...
  • Do Copepods Need Light?

    Let’s start by making one thing clear: There are no animals that “need” light in the way that photosynthetic organisms do. Only plants and certain microbes are capable of performing photosynthesis (“photosynthetic” corals and clams, don’t need light, their endosymbiotic dinoflagellates do)....
  • How do I Acclimate my Copepods?

    One thing we love about copepods is their general hardiness. Since they often live in harsh, unstable natural environments, they are built to withstand a variety of physical and physiological abuses. Generally, when we pour a whole bag full of hundreds of individual pods into the tank, it can be ...
  • How do I know if my Copepods arrived alive?

    The best way to ensure your pods arrived alive and healthy is hold the bag up to a light and look for movement in the bag. Copepods look like small swimming “dust specs” in the water column and near the bottom of the bag. The Tisbe Copepods are typically smaller and they like to congregate at th...
  • How do you Acclimate Copepods?

    Particularly for animals that live in water, jumping 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 harpacticoi...
  • How Do You Know if Copepods are Dead?

    If you just bought a jar of new copepods and can’t see movement within, you might be wondering: How does one know if their copepods have died? The first thing to understand is that copepods are very, very tiny animals. Especially if you don’t have excellent vision, it is quite difficult to see t...
  • How Long Does it Take for Copepods to Reproduce?

    Whether you’re working to build up a good food reserve for a mandarin fish or working on eliminating a disgusting green film that keeps growing over everything, you might be in a hurry to see your problem solved. If you’ve added some copepod seed stock to solve these problems, you might be hoping...
  • What Do Copepods Feed On?

    Copepods are Nature’s trophic intermediaries. That is, they transfer nutrients and food energy from lower (e.g. plants) to higher (e.g. carnivores) levels in the food chain. This also happens to make them nearly indispensable in aquarium systems, where they (1) consume unwanted material such as n...
  • What Do You Feed Copepods in a Refugium?

     Copepods are good. The more, the better. That’s why you want to produce as many as possible. And as fast as you culture them, your corals and small reef fish will eat them! For sure, due to the heavy predation that typically occurs in a reef tank (a single mandarin can eat hundreds of adult cope...
  • What is the best way to add Copepods to my tank?

    The absolute best way to add the copepods to your tank is as follows: Float bag in tank for 10min to acclimate for temperature. Never dose cold pods. Add your Copepods just after the lights in your aquarium turn off. This will allow the copepods time to find a hiding spot before being eaten by h...
  • Will my filtration / pumps kill the Copepods?

    Copepods are very hardy marine organisms accustomed to the strong ocean currents found on natural coral reefs. Typically the water movement in an aquarium is significantly less than in the ocean. Copepods have no problem navigating your aquarium, finding rocks, macro-algae, and other hiding plac...
  • Will Shrimp Eat Copepods?

    Copepods have almost become a staple of marine aquarium systems, serving as (1) algivorous and detritivorous members of the clean-up crew and (2) providing a self-supplying, nutritious live food source for the most finicky corals and small reef fishes. Their presence absolutely makes a ca...
