Best Fish for a 2-Foot Tank in Singapore
The 2-foot (60 cm) aquarium is the most popular tank size in Singapore — it fits on standard furniture, holds approximately 50–65 litres and offers enough space for a beautiful planted community. But choosing the right fish for this size matters. This best fish 2 foot tank Singapore guide from Gensou Aquascaping at 5 Everton Park helps you stock wisely.
What a 2-Foot Tank Can Handle
A 60 cm tank typically holds 50–65 litres depending on dimensions and substrate displacement. At this volume, you can keep small schooling fish, a pair of dwarf cichlids, a small group of livebearers, or a single betta with tank mates. The key limitation is swimming space — active species need the length, while the moderate volume limits total fish numbers. Aim for a total of 15–25 small fish or equivalent bioload.
Top Schooling Fish
Ember tetras (10–12): Tiny, warm orange, peaceful and stunning in a planted tank. One of the best choices for 2-foot setups.
Neon tetras (10–12): The classic choice. Their blue and red stripe pops against green plants.
Harlequin rasboras (8–10): Copper-toned schoolers that are hardy and always active.
Chili rasboras (10–15): Tiny red jewels perfect for densely planted nano-style tanks.
Green neon tetras (10–12): A smaller, more intensely blue alternative to regular neons.
Celestial pearl danios (8–10): Galaxy-patterned micro fish that look incredible in planted setups.
Bottom Dwellers
Pygmy Corydoras (6–8): Tiny catfish that hover in mid-water and rest on plant leaves — unusual and charming.
Corydoras habrosus (6–8): Another dwarf Corydoras species perfect for small tanks.
Otocinclus (3–4): Gentle algae eaters that keep glass and leaves clean. Always keep in groups.
Kuhli loaches (4–6): Eel-like bottom dwellers that hide during the day and emerge at dusk. Need sand substrate.
Centrepiece Fish
Betta (1 male): A single male betta with peaceful nano tank mates is a classic 2-foot setup.
Honey gourami (1 pair): Gentle, golden-coloured labyrinth fish with subtle charm.
Sparkling gourami (3–4): Tiny, iridescent gouramis that actually make audible croaking sounds.
Scarlet badis (1 male + 2 females): Jewel-like micro predators with incredible colour — males are vivid red and blue.
Shrimp Options
Cherry shrimp (15–20): A colony of red cherry shrimp adds colour, movement and algae control. They breed readily and are endlessly entertaining.
Amano shrimp (4–6): Larger, transparent shrimp that are the best algae eaters in the hobby.
Stocking Combinations That Work
Community classic: 10 ember tetras + 6 pygmy Corydoras + 3 otocinclus + 10 cherry shrimp.
Betta paradise: 1 male betta + 6 kuhli loaches + 5 amano shrimp + nerite snails.
Nano stunner: 12 chili rasboras + 6 Corydoras habrosus + 20 cherry shrimp.
Gourami garden: 1 pair honey gouramis + 8 harlequin rasboras + 4 otocinclus.
Fish to Avoid in a 2-Foot Tank
Common plecos (grow to 40 cm), angelfish (need taller, larger tanks), oscars, clown loaches, silver sharks, goldfish and any species that exceeds 8 cm adult size. Also avoid aggressive species like convict cichlids and tiger barbs in groups smaller than ten — they need more space to spread aggression. If a fish shop tells you a large species will “grow to the size of the tank,” that is a myth — the fish suffers, not the tank.
