TRENOYA Microworms – Starter Culture (First Food for Fish Fry)

Description

Microworms (Panagrellus redivivus) are the easiest and most reliable first live food for newborn fish fry in India. These tiny, wriggling nematodes are the perfect size for the smallest mouths and trigger an immediate feeding response that dried foods cannot match. This active starter culture lets you produce a steady supply of nutritious live food at home for the cost of a little oats and yeast.

Why microworms for fry?

The first two weeks decide whether fry survive and grow evenly. Microworms are soft, easy to digest, and rich in protein and fatty acids, giving fry the strong start they need. Because they stay alive in water, fry can graze continuously instead of eating one quick meal.

Frequently asked questions

What fish fry can eat microworms?

Microworms are an ideal first food for tiny fry including betta, guppy, tetra, rainbowfish, gourami and most egg-layers. They are the right size the moment fry become free-swimming.

How long do microworms live in the aquarium?

Microworms stay alive for several hours at the bottom of the tank, giving fry a long feeding window. Add only what fry can eat so leftovers do not foul the water.

How do I harvest microworms?

Wipe the inside wall of the culture container with a cotton bud or clean spatula where worms crawl up, then rinse them into the tank. No sieving needed.

How often should I start a new microworm culture?

Refresh or split the culture every 5-7 days. Starting a backup culture every couple of weeks ensures you never run out during a spawn.

Do microworms smell?

A mild yeasty smell is normal. A strong sour odour means the culture is too wet or overfed; add fresh oats and reduce moisture.
