Fresh Live Phytoplankton – Grown by Rock ’N’ Critters
Our Live Phytoplankton is grown and cultured by us on site at Rock ’N’ Critters.
Rather than buying in pre-bottled phytoplankton and storing it until it sells, we maintain our own live cultures and bottle your phytoplankton when you order it.
That means the product leaving us is as fresh as we can practically make it – living phytoplankton grown specifically for use within marine and reef aquariums.
Why Freshness Matters
Phytoplankton is alive. By growing our own cultures and bottling to order, we minimise the amount of time your phytoplankton spends sitting in a bottle before it reaches your aquarium.
There are no weeks spent sitting on our shelves waiting for somebody to buy it. We culture it here, bottle it fresh and send it to you.
Feed Your Reef from the Bottom of the Food Web
Phytoplankton consists of microscopic marine algae that form one of the foundations of natural marine food webs.
Unlike conventional fish foods, phytoplankton is aimed at some of the smallest inhabitants of your reef, providing suspended microscopic food for suitable filter feeders, zooplankton and other microfauna.
Natural Food for Suitable Filter Feeders
Depending on the species being kept, live phytoplankton can provide food for suitable:
• Filter-feeding corals
• Bivalves and other molluscs
• Feather duster worms
• Sponges
• Tunicates
• Copepods
• Zooplankton and other reef microfauna
Not every coral directly consumes phytoplankton, so we recommend using it as part of a varied reef-feeding strategy appropriate to the animals you keep.
An Excellent Partner for Live Copepods
Our Live Phytoplankton and Live Copepods make a particularly natural combination.
Phytoplankton can provide food for copepods and other zooplankton, while those organisms can themselves become natural live prey for fish and other reef inhabitants.
It's a simple relationship found throughout marine food webs:
Phytoplankton → Copepods → Fish & Reef Inhabitants
For reef keepers looking to establish or support copepod populations, feeding live phytoplankton can therefore be a particularly useful addition.
