Before You Stock: The Basics
A 10 gallon (38L) tank can support more fish than you might think — if you choose wisely. Here's what to consider:
- Cycle your tank first — always essential
- Don't mix aggressive fish — check compatibility
- Consider bioload — more fish = more waste = more maintenance
- Add fish gradually — don't stock all at once
Forget the "1 inch per gallon" rule. It's outdated and misleading. A 10-inch fish won't fit in a 10 gallon tank. Use our combinations below — they're tested and balanced.
1. Solo Betta Paradise
Beginner • Low MaintenanceThe simplest and most stunning option. A single betta with cleanup crew has personality to spare.
Note: Some bettas hunt shrimp. Add lots of plants for hiding spots, or skip shrimp if your betta is aggressive.
