Intan B3 is the next growth-stage crumble (0.4–0.6mm) for juvenile fry that have outgrown B2 — some leftover B2 can still be mixed in during the changeover.

The Breeder & Grower range — B1, B2, B3, and B4 — is a scientific feeding system that takes fish fry from the day they hatch all the way to semi-adult size. Each stage uses a progressively larger soft crumble matched to how big the fry's mouth has grown, so nutrition stays complete and easy to eat at every stage, for both egg-laying (oviparous) and live-bearing (viviparous) species.

Key Features

• Complete nutrition from birth through to semi-adult stage
• Four crumble sizes (B1–B4) matched to fry growth stages
• Soft crumbles suited to oviparous fry and small viviparous species
• Designed to promote healthy growth and proper feeding habits from day one

Best Suited For (Fish Species)

All oviparous fry, plus small viviparous (live-bearing) species such as Guppy, Tangerine, Swordtail, Platy, and Betta fry.

Stage-by-Stage Guide

Each stage (B1, B2, B3, B4) is available in Pouch (1kg) and Mega Pouch (5kg).

Feeding Instructions

Wet the feed so it absorbs water before feeding fry. The feed should be consumed within a few minutes — feed carefully and watch for stomach bulges. Start with a small amount and increase gradually; do not overfeed. Feed again only once the previous feeding has been digested and the stomach is empty. Sort fry by size before moving up a stage, to help prevent cannibalism among different-sized siblings.

Frequently Asked Questions

How do I know when to move my fry from B1 to B2?

Move to B2 about 10–20 days after starting B1, once the fry have grown large enough to comfortably accept a bigger crumble size.

Can I feed B1 and B2 together?

Yes, during the B2 stage some smaller fry in the same batch may still need B1, so feeding both together is fine until all fry catch up in size.

Why do I need to sort fry by size before B3 or B4?

Larger fry can sometimes prey on smaller siblings once they're big enough — sorting by size before each new stage helps prevent this cannibalism.

Is this crumble suitable for guppy and betta breeders specifically?

Yes, the B1–B4 range is suitable for guppy fry, betta fry, and other small viviparous and oviparous species from birth through to semi-adult.

Why does the feed need to be wetted before feeding fry?

Wetting the crumble helps it absorb water and become easier for tiny fry to eat, and helps prevent the dry crumble from expanding uncomfortably in their small stomachs.
