Freshwater Copepods & Daphnia Mix (32 oz Each)

DescriptionFreshwater Copepods & Daphnia Mix – Dual Culture ApproachWe culture both freshwater copepods and daphnia in separate 32oz bottles to give you flexibility in how you feed your fry and nano fish. This two-bottle system lets you rotate cultures or blend them based on what your tank needs. We ship each bottle at peak density—around 8,000-12,000 organisms per 32oz container—ensuring you receive cultures ready to distribute immediately.Our copepods are primarily Mesocyclops and Thermocyclops species, hardy generalists that thrive in freshwater tanks between 68-78°F. The daphnia are mostly Daphnia magna and D. pulex, larger filter feeders that consume algae and small particles. Both organisms reproduce readily when given proper feeding schedules and stable water conditions. We hand-inspect each bottle before shipping to verify density and organism vitality.Dosing & Tank CompatibilityFor nano tanks under 10 gallons: add 5-10ml (1-2 teaspoons) twice weekly. For 10-20 gallon systems: add 15-20ml three times per week. These cultures work with dwarf shrimp, corydoras fry, killifish, and any small-mouth fish under 1 inch. Fry benefit most when dosed daily in very small amounts (2-3ml) rather than one large feeding. Copepods establish populations in gravel, providing ongoing food even between culture additions.Who This Is ForThis product suits breeders managing multiple species, hobbyists wanting backup food sources, and anyone new to natural foods culture who wants simplicity. Having both organisms on hand reduces the learning curve—if your daphnia tank crashes, your copepod bottle remains stable.FAQsQ: Can I mix both cultures together in one tank?A: Yes. Copepods and daphnia coexist in natural freshwater systems. In aquariums, they compete mildly for food but both survive together without predation issues.Q: How long do these cultures last?A: With proper feeding and water changes (20% every 2 weeks), both cultures sustain 4-6 months continuously. We culture ours in-house for 8 months by rotating containers and maintaining 1-2 pH point stability.Copepod Biology & Performance: Our cultures feature multiple copepod species that thrive in diverse aquarium conditions. Copepods measure 300-500 micrometers and reproduce rapidly when fed quality phytoplankton—typical reproduction rates reach 40-60 nauplii per female per week under optimal conditions. These organisms are exceptionally nutrient-rich, containing essential amino acids, omega-3 fatty acids, and carotenoids that enhance fish coloration and immune function. Nauplii (larvae) are preferred by mandarin dragonfish, seahorses, and newly-introduced fish; adults work excellently for cleanup and as supplemental feeding for larger species.Compatible Tank Types & Species:Reef Systems: Mandarin dragonfish, pipefish, seahorses, anemones, corals, clamsNano Tanks: Small gobies, dottybacks, specialized plankton-eatersRefugium Systems: Integrates with macroalgae, maintains biodiversityBreeding Programs: Condition adults, feed nauplii to newly-introduced juvenilesCompatible Invertebrates: Ornamental shrimp, amphipods, isopods, spongesStorage & Handling Recommendations: Keep cultures at 50-65°F for maximum shelf life (refrigerator recommended). For room-temperature storage, use within 10-14 days for optimal potency. Do not expose to direct sunlight. Shake bottles gently before use to ensure even distribution. If cloudiness develops, reduce dosing by half and allow water clarity to return. Cultures tolerate brief temperature fluctuations (48-78°F) but rapid changes stress organisms.Why Choose Our Cultures: I’ve been culturing these organisms for over a decade, and our commitment to quality is evident in every bottle. We test densities before shipping, ensuring you receive exactly what’s advertised. Unlike competitors, we never artificially dilute cultures—every milliliter contains the advertised organism count. Our feeding protocols use minimal additives, resulting in cleaner water and faster-reproducing populations. We personally use these same cultures in our demonstration systems, so we stand behind their performance. When you order from us, you’re supporting small-batch aquaculture rather than mass-production facilities.You May Also LikeFW Copepods only — 32ozFW Daphnia only — 32ozFreshwater Feeds Trio — add phyto too
