Beginner30 L

Cozy Betta tank (30 L)

Easy start: one showy male, shrimp clean-up crew, one plant.

Cozy Betta tank (30 L) — aquarium setup with fish, plants and equipment (30 L)

Minimal setup for a single Betta splendens. Great for an office, bedroom, or as a gift for kids 12+.

Key rule: 30 L is not 'too small' — it's the right size for a betta. Anything less means stress and illness.

Tips & gotchas

  • Keep one male Betta — no other males, no flashy tankmates.
  • Amano shrimp don't breed in freshwater, so the colony stays stable.
  • Do a 30 % water change once a week.
  • Light on for 8 h per day, no more.
