How to Sell Aquarium Fish and Shrimp in Singapore
This sell aquarium fish Singapore guide is for hobbyists whose tanks have become too productive—guppy colonies exploding, shrimp overrunning the moss, or cichlid fry outgrowing the grow-out tank. Selling or rehoming fish responsibly is a skill worth learning, and Singapore has an active marketplace for it. At Gensou Aquascaping, located at 5 Everton Park in Singapore, we regularly connect breeders with buyers and can offer advice on moving your stock efficiently.
Legal Considerations in Singapore
Singapore does not require a licence for hobbyists selling small quantities of home-bred fish on a casual, non-commercial basis. However, if you scale up to regular, high-volume sales, the National Parks Board (NParks) may consider it commercial activity, which requires a licence under the Animals and Birds Act. Importing fish from overseas always requires a permit. Selling endangered or CITES-listed species is strictly prohibited. Stick to common, captive-bred species and keep your activity at a hobbyist level to avoid regulatory issues. When in doubt, check the NParks website or call their helpline for current guidelines.
Best Platforms for Selling Fish Locally
The most active marketplace for aquarium livestock in Singapore is Carousell, where thousands of listings for fish, shrimp, plants and equipment are posted weekly. Create a seller profile, upload clear photos with good lighting, and write honest descriptions including species, size, age and water parameters they were raised in. Facebook groups such as Singapore Aquarium Fish Buy/Sell/Trade and various species-specific groups are also excellent channels. Telegram chat groups for shrimp and betta enthusiasts have grown in popularity. Forums like AquaticQuotient (AQ) still attract experienced hobbyists willing to pay fair prices for quality stock.
Pricing Your Fish and Shrimp
Research current market rates before setting prices. Common guppies sell for $1–$3 SGD each, while fancy strains with established lineage can fetch $5–$15 SGD per pair. Neocaridina shrimp typically go for $1–$2 SGD each in bulk or $3–$5 SGD individually for higher grades. Caridina species like crystal reds command $5–$20 SGD depending on grade. Home-bred bettas range from $5 SGD for basic plakats to $30–$50 SGD for show-quality halfmoons. Price competitively—undercutting shop prices by 30–50 per cent is standard for private sales. Bundle deals (e.g. ten for a discounted price) move stock faster.
Photographing Fish for Listings
Good photos sell fish faster and at better prices. Photograph fish against a clean background—a bare-bottom container with a dark backing works well. Use natural or LED lighting to bring out true colours. Avoid flash, which washes out detail and creates glare. Show the fish from the side to display body shape, finnage and colouration. For shrimp, a macro shot highlighting grade and colour intensity is essential. Include a ruler or coin in at least one image to give buyers an accurate sense of size. Blurry or dark photos will be scrolled past regardless of how good your stock is.
Packaging and Transport
Proper bagging is critical to keep fish alive during transit. Use fish bags filled one-third with water and two-thirds with air—or pure oxygen if you have access to a cylinder. Double-bag to prevent leaks. For short journeys under an hour, a sealed bag in a styrofoam box is sufficient. Add a few drops of water conditioner and, for sensitive species, a small piece of zeolite to absorb ammonia. In Singapore’s heat, transport during cooler morning or evening hours. For shrimp, include a small piece of moss or sponge for them to cling to, reducing stress from sloshing water.
Meeting Buyers Safely
Most transactions in Singapore are conducted via meet-ups at MRT stations or HDB void decks. Choose well-lit public locations and confirm timing in advance to minimise waiting in the heat with bagged fish. Some sellers offer doorstep delivery for a small fee of $5–$10 SGD, which is convenient for both parties and reduces stress on the livestock. For high-value transactions, meet at a neutral location where both parties can inspect the fish before payment. Cash and PayNow are the most common payment methods. Always be punctual—fish in bags have a limited safe window.
Building a Reputation as a Seller
Repeat business and referrals are the backbone of hobby-scale fish selling. Be honest about the quality and health of your stock—disclose any known issues, recent treatments or lineage gaps. Offer a brief acclimation guide with each sale, especially to newer hobbyists. Follow up with buyers after a few days to check that the fish are settling in. Positive reviews on Carousell and recommendations in Facebook groups build credibility quickly. Over time, a good reputation allows you to command higher prices and sell stock faster.
When Selling Is Not the Best Option
If your fish are common species with low demand—such as basic guppies or excess snails—selling may not be worth the effort. Consider donating to local fish shops, which sometimes accept healthy stock in exchange for store credit. Schools, community centres and elderly homes may welcome a donated tank setup. Some hobbyists post free adoption listings on Carousell, which move quickly and keep fish out of unsuitable conditions. Whatever route you choose, never release aquarium fish into local waterways—it is illegal in Singapore and harmful to native ecosystems.
