Copepod Culture Kit | Reefphyto
Buying live copepods every few weeks works, but it adds up. And every time there's a gap in delivery, your mandarin gets stressed, your corals stop extending, and you're back to square one. The real solution isn't ordering more often it's growing your own.
The problem most reef keepers face is not knowing where to start. Culturing copepods sounds technical, but it doesn't need to be. What you actually need is a starter culture of healthy live copepods, the right food to keep them reproducing, a suitable container, and clear guidance. With those four things in place, a thriving self-sustaining population is achievable within four to eight weeks.
The Reefphyto Copepod Culture Kit gives you everything in one box. The Lite Edition includes 250ml of live Tigriopus californicus copepods, 30ml of specialist copepod feed, a 4-litre transparent culture container, and access to our online step-by-step culture guide. The Complete Edition adds an air pump, airline tubing, and a control valve for sustained aeration, ideal if you don't already have an air pump to hand.
Once your culture is established, you have a permanent live food supply on tap. No more worrying about delivery days, no gaps in nutrition, and a significant saving over buying bottled copepods long term. You can harvest directly into your tank or refugium as needed.
Reefphyto has been culturing live marine foods from our specialist facility in Wales since 2008. The guide included with this kit is based on the same methods we use at production scale, adapted for home use. Darren is available personally if you hit any issues or want advice on getting the best results from your culture.

Copepod Culture Kit UK - Grow Your Own Live Tigriopus californicus at Home
Buying live copepods works. But for reef keepers who keep mandarin dragonets, seahorses, or any fish that depends on a continuous live food supply, the gaps between deliveries are a persistent problem. The Reefphyto Copepod Culture Kit is designed to solve that problem permanently, giving you everything you need to maintain a thriving home culture of Tigriopus californicus copepods that you can harvest directly into your tank whenever you need them. No more delivery schedules. No more anxious days when stock is running low. A live copepod supply that you control entirely.
Why Home Copepod Culture Makes Sense for Serious Reef Keepers
For most reef keepers, the decision to culture their own copepods comes from one of two places. Either the cost of regular bottled copepod orders has reached a point where a one-time kit investment makes clear financial sense, or they have experienced enough gaps in their delivery schedule to understand that a mandarin dragonet or seahorse cannot wait for a restock.
Both are valid reasons, and the Copepod Culture Kit addresses both. The upfront cost of the kit replaces the ongoing expense of regular bottled orders. Once a home culture is established and self-sustaining, the only ongoing cost is copepod feed, which is minimal compared to purchasing live cultures month after month. For keepers who order 250ml or more of live copepods every two to four weeks, the kit typically pays for itself within two to three months.
The independence argument is equally compelling. A home culture running continuously means there is always a live copepod supply available, regardless of delivery schedules, bank holidays, or order timing. For a mandarin dragonet that needs to hunt live prey every single day, this continuity is not a convenience it is the difference between an animal that thrives and one that slowly declines.
What Is Included in the Copepod Culture Kit
250ml Live Tigriopus californicus Starter Culture
The starter culture is the most important component of the kit. Freshly cultured at Reefphyto's specialist facility in Wales on the day of dispatch, the 250ml volume provides a meaningful founding population of active, healthy Tigriopus californicus copepods. This is not a token quantity it is a dense, vigorous culture designed to establish quickly and begin reproducing in your home vessel within days of introduction.
The quality of the starter culture determines how quickly your home culture reaches a productive population level. A starter culture that arrives active, well-fed, and in good condition establishes far faster than one that has been in transit too long or has been maintained on an inadequate diet. Every Reefphyto starter culture is dispatched with the same care as a standalone live copepod order.
30ml Copepod Feed
Tigriopus californicus feeds on microalgae and detritus. In a home culture vessel, microalgae must be provided rather than grazed naturally, and the quality of that feed directly determines the growth rate, reproductive rate, and nutritional value of the copepods you harvest. The 30ml copepod feed included in the kit is a specialist microalgae formulation chosen specifically for Tigriopus californicus culture, providing the nutritional base the population needs to grow consistently and remain in good condition.
Regular feeding with a high-quality microalgae feed is the single most important factor in maintaining a productive home culture after the initial population is established. The included feed provides enough to get your culture running, with our copepod feed available separately for ongoing supply once the initial quantity is used.
4-Litre Clear Culture Container
The culture container is sized to give a founding Tigriopus californicus population enough space to grow to a productive harvest density without becoming overcrowded. The transparent design allows you to monitor the culture visually assessing population density, checking for health issues, and observing the copepods' behaviour and activity without disturbing it. Clear containers also allow light to reach the culture, which benefits any residual phytoplankton in the water and the natural behaviour of the copepods.
Step-by-Step Online Culture Guide
The guide included with the kit is built on 16 years of professional aquaculture experience at Reefphyto's Wales facility, adapted specifically for home use. It covers everything from initial setup and seeding through to feeding schedules, harvesting, maintaining water quality in the culture vessel, and troubleshooting common issues. This is not a generic guide assembled from publicly available information it is the method Darren uses and has refined over years of commercial-scale Tigriopus californicus production.
Complete Edition - Air Pump, Airline Tubing, and Control Valve
The Complete Edition adds a silent air pump, airline tubing, and a control valve to the Lite Edition contents. Gentle aeration keeps the culture vessel oxygenated and prevents stratification of the water column, which improves copepod distribution throughout the vessel and supports a healthier, more productive culture. If you do not already have an air pump suitable for a small culture vessel, the Complete Edition provides everything you need to get started without any additional purchases.
How to Set Up Your Copepod Culture
Setting up a home Tigriopus californicus culture is straightforward with the right components. Fill your 4-litre container with marine saltwater at a specific gravity of 1.025 and allow it to reach room temperature. Add your starter culture directly to the container. Begin feeding immediately with the included copepod feed at the recommended rate from the online guide. If using the Complete Edition, set up aeration at a gentle flow enough to keep the water moving without creating turbulence that stresses the copepods.
Within the first week, the founding population will begin to establish and explore the container. By weeks two to four, with consistent feeding, you will see visible population growth and increasing activity in the culture vessel. By weeks four to eight in most setups, the culture is producing enough copepods to support regular harvesting into your tank or refugium.
Harvesting is simple. Gently tip or siphon a portion of the culture volume into your tank or refugium as needed. Replenish the harvested volume with fresh saltwater and resume regular feeding. A well-maintained culture can be harvested repeatedly indefinitely, providing an ongoing live food supply without any further input beyond regular feeding and periodic water maintenance.
Copepod Culture Kit vs Buying Live Copepods - Which Is Right for You
The Copepod Culture Kit and the standalone Live Copepod bottles are not competing products they serve different stages of a reef keeper's live food journey and many keepers use both.
The standalone Live Copepod culture is the right choice for initial refugium stocking, for keepers who are not yet ready to commit to home culturing, or for periodic large-volume additions that supplement an existing home culture. The Copepod Culture Kit is the right choice for keepers who want to reduce the ongoing cost and dependency of regular bottled orders, for those whose fish require a continuous daily live food supply, and for reef keepers who want to understand and control their live food system from the ground up.
For many mandarin dragonet keepers, the ideal setup is a home culture producing regular harvests, supplemented by occasional full culture bottle additions to the refugium to maintain population density and diversity. The Copepod Culture Kit makes the first part of that system straightforward to establish.
Frequently Asked Questions About the Copepod Culture Kit
How long does it take to get a productive culture going?
Most keepers see visible population growth within two to three weeks of setup with consistent feeding. A culture productive enough to support regular harvesting typically takes four to eight weeks depending on room temperature, feeding frequency, and starting population density. The guide included in the kit covers how to optimise each of these factors for faster establishment.
What temperature should I keep my copepod culture at?
Tigriopus californicus is tolerant of a wide temperature range, which is one of the reasons it is so well suited to home culture. Room temperature between 18 and 24 degrees Celsius supports healthy reproduction. Warmer temperatures within this range accelerate reproductive rates. Avoid placing the culture in direct sunlight or near heat sources that could cause temperature spikes.
Do I need the Complete Edition or will the Lite Edition work?
If you already have a small air pump and tubing available, the Lite Edition provides everything else you need and works just as well. If you do not have aeration equipment, the Complete Edition removes the need to source it separately and ensures your culture has the gentle water movement that supports a healthy population from day one.
What do I do if my culture crashes?
Culture crashes are usually caused by one of three things: insufficient feeding, poor water quality in the culture vessel, or temperature extremes. The online guide covers how to identify and address each of these. If you experience a crash and cannot identify the cause, contact Darren directly he is happy to troubleshoot culture issues personally and help you get back on track.
Can I use the kit to culture copepods for a breeding programme?
Yes. Home copepod cultures are used by marine fish breeders as a reliable, on-demand live food source for larvae and juveniles. Tigriopus californicus nauplii produced by an established home culture are an excellent live food for newly settled reef fish and juvenile seahorses, complementing a rotifer-based first-feed programme as larvae develop and require larger prey.
Complete Your Home Live Food System
The Copepod Culture Kit pairs naturally with our copepod feed for ongoing culture nutrition and our live phytoplankton to sustain the microalgae diet that keeps your culture producing consistently. For reef keepers who also culture rotifers, our rotifer culture kit sets up a parallel home rotifer supply using the same approach. For times when your home culture needs supplementing or you want to top up your refugium between harvests, our standalone live copepods and Pod-Shot are available for rapid restocking without disrupting your home culture routine.
