Nano Aquascape Guide: Small Planted Tank Ideas for Desks, Shelves, and Compact Homes
Nano aquascapes — planted tanks under 30 litres — are some of the most beautiful and accessible aquariums you can build. They fit on desks, shelves, kitchen counters, and bedside tables. They require minimal space, modest equipment investment, and — with the right plant selection — very little maintenance. This guide covers everything you need for a thriving nano planted display in Singapore.
What Is a Nano Aquascape?
A nano aquascape is typically:
- Under 30 litres (common sizes: 5, 10, 20, 25 litres)
- 30 cm or shorter in length
- Self-contained: Filter, light, and heater (or no heater) in one compact setup
- Focused on one visual idea: A nano tank cannot accommodate complex multi-element layouts — one strong focal element is more effective
Nano Tank Sizes and What Fits
| Tank size | What fits comfortably |
|---|---|
| 5–10 litres | Single betta, cherry shrimp, or shrimp-only planted |
| 10–20 litres | Small shrimp colony, tiny nano fish (chili rasboras, ember tetras) |
| 20–30 litres | 10–15 nano fish + shrimp, small planted layout |
Best Plants for Nano Aquascapes
Foreground and Carpet
- Monte Carlo: Best carpeting plant for nano tanks — achievable without CO2 under medium light
- Marsilea crenata: Four-leaf clover; grows slowly but stays tidy
- Java moss (flat mat): Zero requirements; excellent ground cover
- Fissidens fontanus: Dense, fine-textured; attaches to smooth rocks beautifully
Midground
- Anubias nana petite (mini): Tiny, dark leaves; perfect scale for nano tanks; attached to tiny pieces of driftwood or pebbles
- Bucephalandra (small varieties): Jewel-like; grows very slowly; ideal scale
- Mini java fern (Microsorum 'Trident' or 'Narrow'): Stays compact; attaches to driftwood
Background and Structure
- Rotala rotundifolia (small bunch): 3–5 stems in the back corner; pink tips add colour
- Small Cryptocoryne parva: Stays under 5 cm; background-level carpet for nano
- Flame moss on driftwood: Creates vertical visual interest without taking floor space
Floating (for shrimp tanks)
- Frogbit (small pieces): Creates natural cover in nano shrimp setups
- Salvinia minima: Tiny; does not overwhelm nano surface like standard salvinia
Hardscape for Nano Tanks
- 1–3 small stones: Ohko dragon stone, Seiryu stone; arrange following rule of thirds
- 1 small piece of spider wood or driftwood: Provides hardscape height and attachment points for epiphytes
- Scale matters: A stone that looks small in a shop can dominate a 10-litre tank — measure before buying
Filtration for Nano Tanks
- Sponge filter (air-driven): The best choice for shrimp nano tanks — gentle flow, no suction risk, biofilm on the sponge surface
- Small internal filter: Works for fish nano tanks; position the outlet to create gentle circulation without a direct flow current that stresses nano fish
- Hang-on back filter: Suitable for 20+ litre nano tanks; intake strainer essential for protecting small fish
Heating Nano Tanks in Singapore
Singapore's ambient temperature (26–30°C) is suitable for most tropical nano fish and shrimp without a heater — assuming the room is not heavily air-conditioned. In heavily air-conditioned rooms, a small nano heater (25W) set to 26°C is recommended.
Best Nano Fish and Shrimp
| Species | Min. tank | Notes |
|---|---|---|
| Chili rasbora | 10 litres | Deep crimson; school of 15+ in 20 litres is stunning |
| Ember tetra | 10 litres | Orange glow; peaceful; stays small |
| Green neon tetra | 20 litres | Smaller than neon tetra; turquoise shimmer |
| Celestial pearl danio | 15 litres | Spotted; very striking in a nano planted tank |
| Pygmy cory | 20 litres | Tiny bottom-dweller; groups of 6 |
| Cherry shrimp | 5 litres | No fish required; breed readily |
| Crystal red shrimp | 10 litres | Advanced; requires RO water |
One-Piece Nano Aquascape Idea: The Mini Diorama (10 litre)
- 1 small piece of spider wood as focal element
- 3 tiny pebbles at the base
- Anubias nana petite and fissidens moss on wood
- Fine black sand substrate
- 10–15 chili rasboras
This setup requires no CO2, no heater, minimal fertilisation, and weekly 20% water changes. It fits on any desk.
