Fry feeding guide

Best live food for gourami fry

Ask gourami breeders where spawns fail and most give the same answer: not the nest, not the hatch — the first week of feeding. Gourami fry hatch at a size that makes betta fry look chunky, and a first food even slightly too big is a total loss. This is the one fry job where vinegar eels are not a preference but the entry ticket.

The feeding plan

Stage	Feed this	Why it works
Days 1–7 (free-swimming)	Vinegar eels, fed at the surface	Among the only cultured foods small enough; they swim in the surface film where gourami fry hang and hunt
Week 2	Banana worms	Smaller and thinner than microworms — the first worm most gourami fry can actually take
Weeks 3–4	Microworms	The productive staple once mouths allow; keep banana worms running for the runts
Week 5+	Newborn daphnia / moina	Growth finally accelerates; uneven batches are normal, so grade by size if cannibalism-by-growth-gap appears

Practical tips

Have the eel tub climbing before the male builds the nest — the timeline from nest to hungry fry is days.
Feed tiny amounts 4–5 times a day at the surface, in still water; fry hang under the surface film and hunt upward.
Raise the first fortnight in a small, shallow volume: food density at the surface is the whole game.

Watch out: Remove the female after spawning and the male once fry are free-swimming — both eat fry. And never “top up” a tiny fry tank with a big water change; gourami fry die of kindness as easily as neglect.

Common questions

What do dwarf gourami fry eat first?

Vinegar eels, for the first week at least. Gourami fry are smaller than betta fry and most cannot take microworms at first — banana worms follow in week 2, microworms in weeks 3–4, newborn moina after that.

Why did my whole gourami spawn die in week one?

Almost always first-food size. If the fry were offered microworms or dry fry food from day one, most could not eat it. Start a vinegar eel tub before spawning and feed at the surface, little and often.
