How We Chose These 10
Selection criteria: fish must be consistently available in Cambodia (either locally bred or through reliable importers), well-suited to Cambodia's warm tropical climate without special equipment, appropriate across a range of experience levels, and genuinely rewarding to keep over the long term. We excluded species that are commonly sold but require care far beyond what most Cambodian fishkeepers can provide without specialist equipment or facilities.
These recommendations come from real-world experience keeping and selling fish in Cambodia, understanding what our customers successfully keep long-term versus what ends in disappointment after a few months.
#1 — Betta Fish (Siamese Fighting Fish)
Difficulty: Beginner to Intermediate. Tank: 20-40 liters minimum (single male). Why Cambodia: Bettas evolved in Southeast Asia — Cambodia is their natural homeland. The warm climate is ideal, local water chemistry suits them perfectly, and they are widely and affordably available.
Bettas are the most individually expressive fish in the hobby. They recognize their owners, have distinct personalities, and display spectacular color and finnage. Available at 4848 OneShop in 47 varieties including Halfmoon, Crowntail, Plakat, Dragon, Galaxy Koi, and Giant.
What to expect: 3-5 year lifespan in good conditions. Relatively low-maintenance once the tank is properly set up. Live alone (one male per tank). Impressive display fish that never fail to fascinate visitors.
#2 — Guppy
Difficulty: Beginner. Tank: 20 liters minimum for a small group. Why Cambodia: Guppies are practically indestructible in Cambodia's warm climate and thrive in local tap water. They breed readily, making them excellent for learning the full fish-keeping cycle from birth to adult.
Premium guppy strains (Moscow Blue, Full Red, Dragon Tail, Neon Blue) available at 4848 OneShop represent the top tier of guppy quality. A small group of quality guppies in a planted 40-liter tank is one of the most beautiful and effortless aquariums possible.
What to expect: constant breeding (if males and females are kept together), active community behavior, wide range of colors and fin shapes. Excellent starter fish that teaches water quality management without punishing every small mistake.
#3 — Flowerhorn Cichlid
Difficulty: Intermediate to Advanced (due to aggression management and waste production). Tank: 200+ liters, single fish. Why Cambodia: Deep cultural affinity with the "dragon fish." Flowerhorns are the most beloved show fish in Cambodian homes and businesses.
No other fish in the hobby matches the flowerhorn for personality and interaction. A well-cared-for flowerhorn recognizes specific people, follows hands across the glass, and responds to feeding time training. The growing kok (nuchal hump) is endlessly fascinating.
What to expect: aggressive toward all other fish, must be kept alone. Large waste producer requiring frequent water changes. Potential lifespan of 10-12 years with excellent care. A commitment, but one of the most rewarding in the hobby.
#4 — Arowana (Silver or Registered Asian)
Difficulty: Advanced. Tank: 400+ liters, long horizontal layout. Why Cambodia: The arowana is the apex prestige fish in Southeast Asian culture — in Cambodia, a healthy arowana is an unmistakable statement of status and care mastery.
Silver Arowana are legally kept and relatively accessible. Asian Arowana varieties require CITES documentation but are available through registered dealers. Either species provides the unique experience of keeping a living prehistoric predator.
What to expect: 20-30 year lifespan, significant ongoing commitment to water quality. Excellent for dedicated fishkeepers willing to invest in proper equipment and regular maintenance.
#5 — Goldfish
Difficulty: Beginner to Intermediate (fancy varieties more demanding). Tank: 40+ liters per fish, cold-optional. Why Cambodia: Goldfish are culturally significant in Cambodia (Khmer New Year celebrations), widely available, and hardy.
Common goldfish and comet varieties thrive in Cambodia without heaters — they actually prefer slightly cooler water (20-24°C) than many tropical fish, which is achievable in air-conditioned rooms. Fancy goldfish (Oranda, Ryukin, Ranchu) require more care but are spectacular.
What to expect: up to 15-20 year lifespan, large waste producers (need strong filtration), cannot be kept with tropical fish that prefer warmer water. Classic, always-crowd-pleasing, and widely understood.
#6 — Neon Tetra
Difficulty: Beginner. Tank: 40 liters minimum, group of 10+. Why Cambodia: Neon tetras are the most recognizable aquarium fish on Earth — that neon blue stripe and red tail make them immediately striking in any planted tank setup.
In Cambodia, neon tetras thrive in room temperature water (25-27°C) without a heater in most homes. They need to be kept in schools of 10 or more to display their natural schooling behavior — a solitary neon is a stressed neon.
What to expect: beautiful schooling behavior, peaceful community fish, affordable (widely available in Cambodia at 500-1,500 KHR each), 3-5 year lifespan. Sensitive to ammonia and poor water — they reward good tank management.
#7 — Corydoras Catfish
Difficulty: Beginner. Tank: 40 liters for a group of 3-6. Why Cambodia: Corydoras are the perfect bottom-cleaning companion fish. They are peaceful, hardy, armored (cannot be eaten by most other fish), and endlessly entertaining to watch.
Sterbai and Bronze Corydoras are the most heat-tolerant species and work well at betta and guppy temperatures (26-28°C). They scavenge leftover food and waste from the substrate, reducing maintenance load. Available in Cambodian fish markets.
What to expect: peaceful schooling bottom fish, must be kept in groups of 3+, live 5-8 years, completely harmless to all other fish. One of the best "support fish" in a community tank.
#8 — Discus
Difficulty: Advanced. Tank: 200+ liters, species-only or with select companions. Why Cambodia: For the serious Cambodian fishkeeper looking for the ultimate challenge and the most visually stunning freshwater fish in the world.
Discus are extraordinarily beautiful but demanding — they need pristine soft, slightly acidic water, high temperatures (28-31°C), frequent large water changes, and high-protein specialized diet. They reward expertise with colors and behavior that no other freshwater fish matches.
What to expect: significant time and financial investment, 10-15 year lifespan, extremely sensitive to water quality. Not for beginners — but the ultimate goal for many experienced Cambodian fishkeepers.
#9 — Koi (Outdoor Pond Fish)
Difficulty: Intermediate. Tank/Pond: 2,000+ liters outdoor pond. Why Cambodia: Koi ponds are a traditional element of Cambodian landscaping, particularly in larger homes, restaurants, and temples. Cambodia's year-round warmth is ideal for koi growth.
Koi grow to 60-90cm in well-maintained ponds and can live 30-50 years with proper care. They are recognizable, culturally valued, and become extremely tame and interactive over time.
What to expect: large pond required, powerful filtration essential, significant investment in quality koi (certified varieties from Japan or Thailand can cost hundreds of dollars), but an extremely long-lived and rewarding pond species for those with the space.
#10 — Snakehead Fish (Native Cambodian Species)
Difficulty: Intermediate. Tank: 200+ liters per adult. Why Cambodia: Snakehead fish (Channa species) are native to Cambodian waterways and deeply embedded in Cambodian food culture. As aquarium fish, they are striking — powerful, intelligent, and adaptable.
Smaller Channa species (Channa gachua, Channa limbata) stay under 30cm and can be kept in 100-150 liter tanks. Larger species (Channa micropeltes — the Giant Snakehead) grow over 1 meter and are suitable only for very large setups.
What to expect: completely Cambodian species that thrives in local water chemistry without adjustment, predatory (cannot be kept with smaller fish), air-breathing labyrinth fish like bettas, highly interactive. A species that connects the aquarium hobby to Cambodia's natural environment.
