🦐 Live culture · currently farming

The clean-up crew nothing else reaches.

A multi-species live copepod blend, cultured in small batches. They graze detritus and biofilm out of every crack and crevice your clean-up crew can't get into — and they're the one food notoriously picky eaters like mandarins and pipefish actually hunt.

$24.99 8 oz bottle Out of stock

Includes: 8 oz (237 mL) bottle of live, multi-species copepods — enough to seed a refugium or feed a display directly.

Why it's better

Cleanup crew and fish food, in one bottle.

Copepods do double duty: they graze detritus, biofilm, and nuisance algae out of spots your snails and hermits never reach, and they're the natural prey species that picky fish are actually wired to hunt.

🦐

Multi-species blend

Different sizes and habits in one bottle — some graze rock and glass, others hang in the water column as feeder prey.

🐠

Feeds picky eaters

Mandarins, pipefish, and many fry rely on live pods and won't reliably take prepared foods.

🧹

Grazes what your CUC misses

They get into cracks, crevices, and rockwork that snails and hermits can't reach.

🧪

Small-batch cultured

Grown and bottled fresh in small batches, so what you get is dense and actively reproducing.

🌊

Builds refugium biodiversity

Add them to a refugium and let the population establish itself, restocking your display over time.

❄️

Shipped cold

Packed to keep the culture calm and alive in transit, so it arrives ready to add.

How to use it

Seed it and let it grow.

Copepods establish best with time and a low-flow, low-predation space to reproduce.

Acclimate gently

Float and drip-acclimate like any live arrival before adding them to your system.

Add to a refugium

A connected refugium with rubble or chaeto gives the population cover and room to multiply.

Feed the culture

Dose live phytoplankton nearby to keep the population fed and growing.

Let it establish

Give it a few weeks before expecting a visible bump in your display — populations build gradually.
