Live Copepod Aquaculture, Microscope-Verified Before Every Bottle

What CopepodsForsale.com Does

CopepodsForsale.com is a working aquaculture facility. We culture live copepods, phytoplankton, and chaeto in-house and ship them across the United States, fast. Coast to coast, we get live food to your tank in days, not weeks.

Same-Day Harvest, Same-Day Ship

Every order goes straight from the active culture to the bottle to the box, the same day it leaves us. There is no warehouse step. No reseller. No shelf time. The bottle on its way to you was filled hours earlier from a living, growing culture. That is how live food is supposed to arrive.

Microscope-Verified, Every Culture

Before anything is bottled, we look at it under the microscope. Every culture, every time. We check density, motility, and species composition with the same care we would use if it were going into our own display tank, because that is the standard we hold ourselves to. If a culture is not right, it does not ship.

What We Culture

Five copepod species, each picked for what it does best:

• Tisbe biminiensis — benthic substrate dwellers
• Tigriopus californicus — high-protein surface activity
• Apocyclops panamensis — mid-water feeders
• Oithona colcarva — fine particle grazers
• Euterpina acutifrons — nutrient-dense, picky eater bait

Plus six-species saltwater phytoplankton, freshwater Tetraselmis, Nano, and Chlorella cultures, F-2 fertilizer made fresh, and freshwater live foods like daphnia, moina, rotifers, microworms, and seed shrimp.

Lab-Grade From the F-2 Up

The foundation of every culture is the food we feed it. Our F-2 fertilizer is mixed in-house from lab-grade ingredients. The phytoplankton our copepods eat is grown 100% sterile, the way a research lab would do it, because the only standard worth holding is the highest one. Quality at the base means quality in the bottle.

Pest-Free Chaeto You Can Trust

Our chaeto is grown in dedicated systems with no fish, no coral, no shared water. We dose only the nutrients chaeto needs to thrive, nothing else. When it arrives at your tank, you do not have to worry about hitchhiking pests, parasites, ich, or anything else your fish or coral could catch. Just clean, healthy macroalgae ready to do its job.

Density You Can Verify

Pour any of our bottles into a clear container. The pods are visible. The phyto is opaque green or amber. We do not dilute and we do not pad bottles with water. We would rather you see what you are paying for than read a marketing claim about it.

Shipping & Guarantee

Every order ships free with our arrive-alive guarantee. Most orders go out the same day they are cultured and reach customers in 1 to 3 days. If anything arrives in poor condition, we replace it. No claim form, no photo deadline pressure.
