Mandarin Keeper Hub

Everything you need to keep a mandarin dragonet fed

The mandarin is not difficult to keep. It is difficult to feed. Get the feeding right and everything else falls into place. This page brings together the checks, tools, live food and guides I have built over 18+ years of helping reef keepers with mandarins.

Plan your mandarin's copepod supply

The Feeding Schedule Builder has a mandarin path. Tell it your tank size and where your copepods live, and it works out how often to order, adds a PodHide if you have no refugium, and picks the cheapest pack at today's prices.

The belly check

Is my mandarin getting enough to eat?

Look at your mandarin from above, once a week. The belly tells you whether the copepod supply is keeping up.
Flat or rounded bellyYour mandarin is fed. The food supply is keeping up, so carry on as you are.
Pinched bellyFeed more. Add live copepods now and look at how often you are ordering. If you are not sure what to change, ask me.
Where are you now?

Choose your starting point

Whether you are researching your first mandarin, worried about one that is struggling, or looking after one long-term, start with the path that fits.

I am thinking about getting a mandarin

The most important work happens before the fish goes in: a mature tank, somewhere for copepods to breed, a population already established, and tank mates that will not eat its food. Use the checklist above, then read these.

My mandarin is struggling

A pinched belly, faded colour or less hunting usually means the tank is not producing enough food. The fix is almost always more copepods, added regularly. Live copepods cannot be stored, so the whole pouch goes in the day it arrives.

I want my mandarin to thrive long-term

Your mandarin is settled and eating. Now the aim is a food supply that looks after itself: copepods breeding in the tank, phytoplankton to keep them breeding, and a culture of your own if you want one.

A note from Darren

I have been helping reef keepers feed mandarin dragonets since 2008. The ones whose fish reach year five, six, seven are not doing anything extraordinary. They built the system before the fish went in. They kept the copepod supply consistent. They paid attention. If you are thinking about a mandarin or struggling with one, talk to me. I would rather spend twenty minutes helping you get it right than see another fish lost to a problem I know how to solve.
