Safe Separation for Breeding, Hatching & Recovery

Give your baby fish, shrimp, and betta fry a protected space to thrive. This clear acrylic isolation box mounts inside your existing tank via suction cups, maintaining the same water temperature and chemistry while keeping vulnerable fish safely separated from the main tank population.

Features

  • Clear acrylic construction — monitor fish easily without disturbing them
  • Permeable mesh gaps — allows water flow while preventing escape
  • Hatching partition included — separate adults from eggs or fry
  • Feeding hole on top — feed without removing the box
  • 2 strong suction cups included — mounts securely to any tank wall
  • No electricity required — fully passive, safe for all tank setups

Ideal For

Breeding betta fish, isolating injured or aggressive fish, hatching eggs, protecting baby shrimp, and quarantining new fish before introducing them to the main tank.

Sizes

  • Small — 8 × 7 × 10cm | Best for nano tanks and small breeders
  • Large — 10 × 7 × 13cm | Best for medium to large tanks

Includes: 1 isolation box + 2 suction cups. Decorations not included.
