What is a Tabletop Aquarium?

A tabletop aquarium is a small, decorative fish tank designed to be placed on a table, desk, or other elevated surfaces. They usually range from 1 to 10 gallons in capacity, though some larger tabletop designs can go up to 20 gallons depending on the available space.

Unlike large aquariums, tabletop tanks are compact, easy to move, and perfect for people who want the beauty of aquatic life without dedicating an entire wall or corner of a room.

These aquariums are popular in homes, offices, dorm rooms, restaurants, and even spas where space is limited but aesthetic appeal is a priority.

Choosing the Right Tabletop Aquarium

When selecting a tabletop aquarium, consider the following factors:

Best Fish for Tabletop Aquariums

Because tabletop aquariums are small, it’s important to choose species that thrive in limited space.

1. Betta Fish

A single betta fish is the classic choice for tabletop aquariums due to its vibrant colors and low space requirements.

2. Guppies

Small, hardy, and colorful, guppies do well in groups in 5+ gallon tanks.

3. Endler’s Livebearers

Similar to guppies, they’re perfect for nano tanks.

4. Neon Tetras

Peaceful schooling fish ideal for tanks 5 gallons or larger.

5. Shrimp

Cherry shrimp or Amano shrimp are great for planted tabletop tanks.

6. Snails

Nerite snails or mystery snails act as natural cleaners and add variety.

Best Plants for Tabletop Aquariums

Adding live plants improves water quality and creates a natural look.

Java Fern – Hardy and low-maintenance.
Anubias Nana – Compact and great for small tanks.
Java Moss – Provides shelter for shrimp and fry.
Hornwort – Excellent oxygenator.
Dwarf Hairgrass – Creates a carpet-like effect.
Floating Plants (Duckweed, Frogbit) – Add shade and help reduce algae.

Essential Equipment for a Tabletop Aquarium

Even small aquariums require proper equipment to ensure fish health.

1. Filter

A sponge filter or small hang-on-back filter keeps water clean.

2. Heater

If you’re keeping tropical species, a small heater maintains stable temperatures.

3. Lighting

LED lights designed for nano tanks highlight fish and support plant growth.

4. Substrate

Choose gravel, sand, or aqua soil depending on plants and fish.

5. Lid or Cover

Prevents fish from jumping and keeps dust out.

Step 4: Hardscape Design
