Keeping a 10-gallon planted aquarium is a great way to enter the aquarium hobby. With the right fish and proper planning, your small tank can be a thriving aquatic ecosystem. But what are the best fish for a 10-gallon tank with plants? In this guide, we’ll explore top fish choices, compatibility tips, and care requirements so you can build a peaceful and beautiful aquarium.
1. Why Choose a 10-Gallon Planted Tank?
Planted tanks are not only visually appealing, but they also provide natural filtration, oxygenation, and hiding spots for your fish. A 10-gallon tank offers a compact setup ideal for beginners, apartments, or desktops. The key is to pick fish species that thrive in smaller, stable environments.
Benefits of plants in a 10-gallon tank:
- Natural biofiltration
- Reduced algae growth
- Stress reduction for fish
- Aesthetic beauty
2. Best Fish for a 10-Gallon Tank with Plants
Here are some of the best species that do well in planted tanks and limited space:
Betta Fish (Betta splendens)
- Temperament: Territorial, but peaceful if kept solo or with non-fin-nipping tankmates
- Why it's great: Colorful, hardy, and low bioload
- Tip: Avoid strong currents and aggressive tankmates
Neon Tetras (Paracheirodon innesi)
- Temperament: Peaceful, schooling fish
- Group size: 6+
- Why it's great: Bright colors pop against green plants
- Tip: Provide plenty of hiding spots and soft lighting
Guppies (Poecilia reticulata)
- Temperament: Peaceful
- Why it's great: Active, easy to breed, and vibrant
- Tip: All-male groups help prevent overbreeding
Chili Rasboras (Boraras brigittae)
- Temperament: Very peaceful, nano fish
- Group size: 8-10
- Why it's great: Tiny size, bright red color
- Tip: Dense planting helps them feel secure
Pygmy Corydoras (Corydoras pygmaeus)
- Temperament: Peaceful bottom dwellers
- Group size: 6+

3. Fish to Avoid in a 10-Gallon Planted Tank
Some species outgrow a 10-gallon tank or are too aggressive. Avoid:
- Goldfish (too messy and large)
- Angelfish (grow large, semi-aggressive)
- Gouramis (some are too territorial)
- Plecos (even "dwarf" ones get big fast)
4. Compatibility & Stocking Tips
General rule: 1 inch of fish per gallon, but consider activity level, bioload, and territory.
Great combinations:
- Betta + Shrimp or Snails (with caution)
- Neon Tetras + Pygmy Corydoras
- Guppies + Cherry Shrimp
Avoid mixing:
- Multiple male Bettas
- Fast nippers with Betta fish
Beginner mistake: Overcrowding or adding all fish at once. Cycle your tank and add slowly!
5. Care Tips for a Healthy Planted Tank
- Water changes: 25% weekly
- Lighting: 6–8 hours daily (use a timer)
- Plants: Java Fern, Anubias, Amazon Sword, Duckweed
