Beginner30 L
Cozy Betta tank (30 L)
Easy start: one showy male, shrimp clean-up crew, one plant.
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.
