Mandarins hunt live copepods all day

They need a tank that is at least 12 months old and a copepod population that keeps up with them. Regular top-ups of live copepods help keep that population going.

Culturing marine food since 2008

Reefphyto began in Wales with Darren and a passion for marine aquaculture. We still grow the live foods ourselves, and Darren still answers the questions.

Superb quality product and extra special customer service. I can't recommend this company enough. My orders always come well packaged and my reef is thriving. An independent company that goes the extra mile!

Darren was great and kept me informed of their processes to align with our quarantine procedures with introducing new water sources to our tank. We had previously bought phytoplankton and started a culture and it had been productive and easily setup with the instructions provided.
