Pods in Reef Tank

Are There Copepods in Your Reef?

by Sean Taj

Are There Pods in Your Reef?

Copepod Culture
Copepods are an integral part of nearly all natural marine ecosystems, and it’s likely that a large, stable population of copepods can benefit any reef aquarium. The surest way to establish a lasting copepod population in your reef tank is by seeding the aquarium system with a healthy, mixed-species starter culture.

The benefits of adding pods don’t end there. It’s equally important to periodically boost an established population with supplementary cultures. Each addition of a quality mixed-species and mixed-life stage product, such as 5280 Pods, provides a surge of food energy to filter-feeding invertebrates (e.g., corals) and pod-eating fish (e.g., mandarin fish and seahorses). Moreover, new pods that escape predation contribute biomass and genetic diversity to your existing population, helping to ensure its long-term stability.

[Copepods]

How to Start a Population of Copepods in Your Reef Tank

When receiving a copepod starter culture, it’s normal to expect a few dead individuals due to their short lifespan. A healthy culture will show signs of movement, especially under a bright light. Mixed-life stage products, such as Poseidon’s Feast, include both larger, visible adults and smaller individuals from earlier life stages, promoting rapid establishment of large, stable populations.

After introducing a fresh culture into your reef, give the pods time to adjust. Some will inevitably fall prey to fish or other invertebrates, but many will settle onto the rock or substrate, feeding on detritus and avoiding predators. It takes 4-6 weeks for the first generation of pods to become visible, and it may take several months for the population to grow large enough for observable activity in the tank.

Signs of an Established Copepod Population

A thriving copepod population will result in various signs of improved reef health. Corals should expand their feeding tentacles at night, and small pod-eating fish like flame wrasses and scooter blennies will appear well-fed and active. You may also notice reduced microalgae growth, slower detritus accumulation, and cleaner live rock and sand.

Despite these benefits, copepods can be hard to spot. They are small and tend to be more active at night. To find them, use a flashlight to scan the sand surface and water column at night. Look for tiny beige or reddish dots moving about. A microscope can offer even greater insight, allowing you to observe copepods of all life stages. Collect a water sample from the detritus during routine tank cleaning for observation.

[Copepods]

Copepod Starter Cultures: A Growing Investment

A mature reef aquarium surely has thousands upon thousands of copepods!
The rate at which a starter culture grows depends on several factors, including predation and food availability. To minimize predation, introduce the culture at night or into the refugium, if possible. Growth also depends on the amount and quality of food available.

Do you want your resident copepods to thrive? Feed them. While copepods will naturally feed on detritus and microalgae, most species also rely on phytoplankton during their planktonic life stages. Supplement their diet with a live phytoplankton product like OceanMagik, a live, multispecies blend that enhances copepod productivity. Many essential vitamins and fatty acids are synthesized by phytoplankton and transferred up the food chain from phyto to pods to fish and invertebrates. Learn more here.

Adding copepods to your reef is simple. Purchase a quality live copepod product, introduce it at the right time and place, and wait. If your tank has detritus or film algae, and places for the pods to hide, a population will likely establish within a few months. Regular boosts will ensure that the population continues to clean the tank, provide food for other tank inhabitants, and thrive for as long as your system is running.

    If you get the copepods and the phytoplankton, should you combine them separately for a while before adding to the aquarium, to give the copepods time to eat?

    If you want to look at them under a microscope, will sucking up some water into a pipette pick them up, or are they too big to fit in?

    How do copepods do in brackish water (15 ppm salt)?

    Since the beginning of the setting I seed pods, I still see some at the refugium. And once I don’t see them I add more to the display and the refugium. They are great scavengers and my corals and fishes love them. It’s part of my biodiversity.

      does dosing this cause higher nitrates and phosphates? i know that happened once I got corals and started feeding reef roids and occasionally mysis shrimp! do you think they could stay alive on reefroids which is zooplankton? I dont have a skimmer so some of it stays in my tank! Small 10 gallon’ I have a yellow clown goby that wont eat and I have noticed i am getting pods just from tank maturing but probably not enough to keep him norised. I dont want to spoil him though, prefer no pods and him eatting pllets like the 2 clowns do but i defiently want pods in my bigger system that has a sump and is almost cycled!

    I have some in my tank that came in on rocks. They took a few months to populate, but I seem to have a lot now. I do wonder if adding one of your mixes would still be a good idea since I don’t know what kinds I have.

    I dropped 2 jars of posd in my fuge months ago and have a booming population. It’s awesome. I actually got into reefkeeping because of pods, I was raising them for betta fry and just decided to add more to the pod tank. Now I’ve got multiple tanks and fuges going. Pods are my gateway critter ?

    Interesting watching them move around in the rocks. You can also see them at night if you shine a flashlight on the rocks.
