ZollaBox Fish S: Grindal worm breeding kit for small fish (up to 5 cm)
What is the ZollaBox Fish S?
A ready-to-use kit for easily breeding your Grindal worms at home and providing perfectly suitable live food for small-mouthed fish (guppies, neon tetras, bettas, fry, etc.). The kit includes the culture pot with lid, natural substrate, live culture, glass support, special food, a harvesting brush, and step-by-step instructions in French.
Why use the ZollaBox Fish S in a natural aquarium?
- Suitable live food: perfect size for small fish and fry that have passed the micro worms stage.
- Stimulates appetite and breeding: Grindal worms are known to trigger spawning.
- Self-sufficiency: avoids dependence on industrial foods by allowing regular harvesting all year round.
- Simple and clean: guided, easy culture, all equipment provided, healthy culture included, food provided, no odor.
- Sustainable: renewable culture at low cost thanks to available food refills.
- Stimulates the hunting instinct: your fish recover their vital natural instinct to search for and capture small prey. This is their “anti-depression” advantage.
Who is the ZollaBox Fish S for?
- Beginners who want to feed their fish naturally (guppies, bettas, neon tetras, tetras, etc.).
- Experienced aquarists seeking a simple, healthy breeding setup to avoid artificial food.
- Breeders of fry from all species.
- Educational projects in low-tech aquariums.
Installation and usage tips
- Set up the culture pot with the supplied natural substrate.
- Inoculate it with the live culture and feed it with the special food (very little at first).
- Be patient: you generally need to wait 3 weeks for the worms to colonize the substrate, reproduce there, and then come to feed on the glass slide.
- Harvest cleanly from the glass support with the brush, then distribute directly without rinsing.
- Keep your culture going for a long time with the ZollaBox Fish S refill (without having to buy another kit).
FAQ - ZollaBox Fish S
When can I harvest the first Grindal worms?
Generally after 3 weeks or one month, once the culture has become established. After that, harvesting is continuous.
Which fish benefit from them the most?
All small tropical fish (guppies, dwarf tetras, killifish, bettas) and fry after the micro worms stage. Corydoras love anything worm-shaped (worm-like prey).
What is the difference compared with daphnia or micro worms?
Grindal worms are meatier and highly palatable; they complement daphnia perfectly and therefore help vary the menu. Larger than micro worms, they come next in the fry feeding schedule.
How long does the culture last?
Indefinitely, provided you maintain hygiene, feed moderately, and use refills when the supplied food runs out.
Is it suitable for nano aquariums?
Yes: small portions for small fish, with no pollution as long as feeding is reasonable.
