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 firstalways 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 It's outdated and misleading.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 Maintenance

The 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.

🌈

2. Classic Community

Beginner • Active

The quintessential starter community. Colorful, active, and forgiving of mistakes.

22-26°C (72-78°F) pH 6.5-7.5

3. Neon Paradise

Intermediate • Stunning

Maximize the schooling effect with a larger group of tetras. Mesmerizing to watch.

Pro tip: Add black substrate to make neon colors pop. Plants and driftwood create the natural Amazon look.

🦐

4. Shrimp Colony

Beginner • Low Bioload

A thriving shrimp colony is endlessly fascinating. They breed easily and are perfect for planted tanks.

Bonus: Shrimp have almost zero bioload. This tank needs minimal maintenance once established. Colony can grow to 50+ shrimp!

5. Guppy Garden

Beginner • Colorful

Guppies are bulletproof and come in endless color varieties. Males only = no babies and maximum color.

Warning: If you add females, expect babies within weeks. They can store sperm for months!

🌿

6. Planted Showcase

Intermediate • Natural

A nature aquarium with algae-eating crew. The plants are the star; fish complement them.

Note: Otos are sensitive — add them only to established, mature tanks with algae growth.

💎

7. Nano Schoolers

Intermediate • Elegant

Tiny fish, big impact. Celestial pearl danios are like swimming jewels.

Pro tip: CPDs are shy at first. Dense planting helps them feel secure and show their best colors.

8. Oddball Characters

Intermediate • Unique

For those who want something different. Kuhli loaches are like aquatic noodles.

Fun fact: Sparkling gouramis actually make audible croaking sounds! You can hear them across the room.
