Three Spot Gourami Care Guide: Trichopodus Trichopterus

The three spot gourami is the fish that taught a generation of Singapore hobbyists what a labyrinth organ actually does; drop one into a half-cycled tank and watch it thrive while its tetra tankmates struggle. This three spot gourami care guide from Gensou Aquascaping in Singapore covers everything from tank sizing to breeding this bulletproof anabantoid. Trichopodus trichopterus is neither small nor delicate, which surprises keepers expecting a betta-sized fish. Understanding its adult footprint and mild territoriality is the key to a successful long-term setup.

Quick Facts

• Adult size: 12-15 cm
• Water: pH 6.0-8.0, GH 2-15, highly adaptable
• Temperature: 24-30°C
• Minimum tank: 150 litres for a small group
• Lifespan: 5-8 years

Why It Is Called Three Spot

The name refers to two lateral body spots plus the eye, which the fish counts as the third. Wild-type colouration is grey-blue with subtle vertical banding. The species has been bred into gold, opaline, lavender, and platinum colour morphs, all sharing identical care requirements. A mixed group of colour forms in one tank makes a visually striking display without crossbreeding concerns.

Tank Size and Footprint

Adults reach 15 cm and need horizontal swimming space. A 120 by 40 cm tank holding 150 litres is the practical minimum for a group of 4-6 fish. In HDB flats, factor in floor load; a stocked 150-litre tank weighs around 200 kg with substrate. Position against a load-bearing wall and avoid placement over cabinets without a dedicated tank stand.

Water Chemistry

Three spot gouramis tolerate Singapore PUB tap water directly after dechlorination. Aim for pH 6.8-7.5 and GH 3-8. They handle temperature from 24-30°C comfortably, which means no heater in most Singapore flats. A hang-on-back filter or small canister rated for 2-3 times tank volume handles the bioload; avoid aggressive surface agitation since the fish breathes atmospheric air via its labyrinth organ.

Diet

Omnivorous and greedy. Offer a staple pellet like Hikari Cichlid Gold small, supplemented with frozen bloodworm, mysis, and vegetable flakes. Blanched courgette or spinach once a week provides fibre and reduces bloat. Feed twice daily, removing leftovers. Adults happily eat hydra and planaria, which makes three spot gouramis useful cleanup crew for infested tanks.

Behaviour and Tank Mates

Males become territorial during breeding but are otherwise moderately social. Keep one male with 2-3 females to spread aggression. Compatible tankmates include angelfish, silver dollars, peaceful cichlids like keyhole and rainbow, medium-sized barbs, and large rasboras. Avoid slow-moving long-finned fish; adult gouramis nip fancy guppies and bettas without hesitation.

Bubble Nest Breeding

Breeding is straightforward. Raise temperature to 28°C, lower water to 20 cm, and add floating plants. The male builds a large bubble nest under a leaf and courts the female via flaring and tail wraps. Spawning yields 500-1000 eggs, far more than most anabantoids. The male guards the nest; remove the female immediately after spawning. Fry hatch in 24 hours and free-swim at day 3.

Fry Rearing

First food is infusoria for 3-4 days, then baby brine shrimp and microworms. Frequent small water changes prevent ammonia buildup. Labyrinth organ development requires humid air above the waterline; seal the tank with cling film for the first 3 weeks to maintain a warm, humid microclimate. Survival rates of 200-400 fry per spawn are achievable.

Sourcing in Singapore

Wild-type, gold, opaline, and lavender three spot gouramis are staples at every LFS from C328 Clementi to Seaview Pasir Ris. Juveniles priced at $3-6 grow rapidly. Quarantine for 10-14 days; wholesale imports occasionally carry tuberculosis, which presents as progressive wasting and spinal deformities. Cull suspected cases promptly to protect other tanks.
