Live food for pea puffers

Pea puffers are micro-predators: many individuals simply do not recognise pellets as food. Live prey that moves through the plants is what they evolved to hunt — daphnia for daily hunting, grindal worms for a meatier feed.

The feeding plan

Stage	Feed this	Why it works
Daily hunting food	Live daphnia scattered through the tank	Puffers stalk and pick them off one by one — enrichment and nutrition in one feed
Meatier feeds, few times a week	Grindal worms	A substantial worm a pea puffer can tear into; good for keeping condition on smaller or shy fish
Shy or new fish	Small live daphnia, lights low	Live movement is the most reliable way to get a fasting puffer eating again

Practical tips

Feed in the plants, not in open water — puffers hunt by stalking from cover.
In a group, spread food widely so bold fish do not monopolise one feeding spot.
A daphnia culture means a shy fish can be tempted daily without buying live portions every week.

Watch out: Pea puffers also need hard foods (like snails) in the wider diet to wear their ever-growing beaks — live daphnia and worms are excellent food, but not beak maintenance. Keep the rest of the diet varied.

Common questions

Will pea puffers eat daphnia?

Yes — daphnia is one of the most reliable pea puffer foods. The swimming movement triggers their hunting response, which dry food often fails to do.

My pea puffer won’t eat pellets. What now?

Start with live daphnia and grindal worms — movement is usually the missing trigger. Once eating confidently, keep live food as the core and treat prepared foods as optional extras.
