Neocaridina Mystery Box

🫧 Signature Mystery Boxes – Breeder’s Choice

Choose your box size.

We take care of the rest.

Our Signature Mystery Boxes are curated entirely by the breeder once your size is selected. Customers choose 15+ shrimp or 30+ shrimp — all colour selections, mixes, and combinations are then chosen at random from our signature range and current stock.

Each box may contain:

• One large, cohesive group from a single signature selection, or

• A combination of multiple signature selections, chosen for balance, contrast, and overall impact.

The exact outcome is never guaranteed — and that’s the heart of the mystery.

✨ Available sizes:

• 15+ Shrimp Mystery Box

• 30+ Shrimp Mystery Box

Final selection and composition are breeder’s choice.

🐚 Perfect for:

• Shrimpkeepers who enjoy true surprises

• Building or expanding established colonies

• High-impact tanks needing instant presence

• Those who trust the breeder’s eye for balance and quality

💡 How this differs from Signature Surprise Bags:

• Signature Surprise Bags (5 & 10) offer smaller, curated groups

• Mystery Boxes focus on scale, unpredictability, and breeder-led selection

🦐 Shipped with care, including insulation, heat packs when required, and H&K Aquatics’ trusted “extra care” packaging.

Key details:

• Minimum 15+ or 30+ Neocaridina shrimp
