64 oz Freshwater Pods

DescriptionFreshwater Copepods – 64oz Large CultureWe double the density of our standard 32oz bottle by providing 64oz of freshwater Mesocyclops and Thermocyclops at full strength—15,000-25,000 organisms per container. This size targets breeders running parallel fry batches, hatchery operations, or anyone maintaining multiple 20 gallon systems. The 64oz format maintains density reliability while offering extended culture viability; larger water volume resists pH swings and temperature spikes that destabilize smaller bottles. We ship in dual-sealed containers to prevent spillage and ensure each compartment receives identical inspection and quality control.Copepods from this batch enter your tanks at nauplii, juvenile, and adult life stages simultaneously, providing immediate feeding opportunities across fry size ranges. Females gravid with 50-100 nauplii are included at full density. Once established in your tank, this inoculation sustains a population for 8-12 weeks without additional dosing, though we recommend light phytoplankton feeding (2ml weekly) to accelerate reproduction and population stability.Distribution StrategySplit the 64oz across two 20-gallon fry tanks (32oz each), or establish a 40-gallon dedicated culture system. Perform 20% water changes bi-weekly. Maintain 68-76°F. In established systems with moderate bioload, copepods reach maximum density (500 per gallon) within 4 weeks. This timing aligns perfectly with growing fry transitioning from nauplii to juvenile food sizes—copepod population growth mirrors fry appetite expansion.Who This Is ForCommercial breeders, multi-species hobbyists, and aquaculturists scaling from single-culture systems into multi-tank operations without complexity.FAQsQ: Is the 64oz worth buying instead of two 32oz bottles?A: Yes. You receive higher total density and save on shipping costs. The larger volume also provides better population stability for long-term tank establishment.Q: Can I split this bottle between multiple tanks?A: Absolutely. Divide equally across 2-4 systems depending on tank size. Each portion establishes independently within 3-4 weeks.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 LikeAlso available in 32ozUpgrade to 1 gallonAdd FW Phytoplankton to feed your pods
