Looks how to spot one

Scaled, small arrow-shaped labyrinth fish

A tiny, arrowhead-shaped gourami with one solid dark stripe along the side and a second row of dark blotches above it. Under good light its body and fins shimmer with red, green and blue, and its eyes can look bright blue. Males are more vivid and have longer fins than females.13

ColoursIridescent blue-greenRed spottingDark lateral stripe31

Personality what they are like

A small, peaceful fish that is a little shy. Males display to each other and to females with fin-spreading and soft croaks.13

Daily activity how busy a day looks

Moves calmly among plants, mostly in the middle and upper water, and takes air from the surface.13

Grooming and care the hands-on bits

A well-planted tank with surface cover and gentle water flow, plus regular partial water changes.1

Home where they are happiest

Tank with a base of at least 45 x 30 cm (about 40 litres). Temperature 22-28 °C, pH 5.0-7.5, hardness 1-12 dGH.1

Food basics what goes in the bowl

Eats small insects and invertebrates in nature. Accepts dried foods, but give plenty of small live or frozen foods such as daphnia, brine shrimp or bloodworm.12

Company who they like around

Keep as a pair or small group with other peaceful, small fish like small cyprinids or loaches. Very small shrimp may be eaten.1

The story where it all began

J. P. Arnold described it in 1936 under the name Ctenops pumilus. It later moved to Trichopsis and became a popular choice for small planted aquariums.3

Fun facts for the dinner table

  1. 1

    Males and females 'croak' using a special mechanism in the pectoral fins, which you can sometimes hear outside the tank.1

  2. 2

    It is one of the smallest gouramis, reaching only about 4 cm.1

  3. 3

    It lives happily in low-oxygen places like rice paddies thanks to its air-breathing labyrinth organ.3

  4. 4

    Males build small bubble nests, often under leaves or in tubes, and guard the eggs.1

Owner questions the things everyone asks

How often should I feed my Sparkling Gourami?

Feed your Sparkling Gourami small amounts once or twice daily. Furry Diary's starting plan suggests feeding every day. Offer a variety of small live or frozen foods like daphnia and brine shrimp.12 Furry Diary plan

What does a Sparkling Gourami eat, and what should it never eat?

Your Sparkling Gourami enjoys small insects and invertebrates, so offer small live or frozen foods such as daphnia, brine shrimp or bloodworm, along with dried foods. For foods to avoid, it's best to ask your vet or a good breeder.12

How much space does a Sparkling Gourami need?

Your Sparkling Gourami needs a tank with a base of at least 45 by 30 centimetres, which is about 40 litres. This gives it enough space to swim calmly among plants.1

What temperature, light or water does a Sparkling Gourami need?

Keep the water temperature between 22 and 28°C, with a pH of 5.0 to 7.5 and hardness of 1 to 12 dGH. A well-planted tank with surface cover and gentle water flow is ideal for this peaceful fish.1

How often should I clean a Sparkling Gourami's home?

Furry Diary's starting plan includes a weekly 25% water change, weekly glass cleaning, and a monthly filter rinse using old tank water. Regular partial water changes help keep your gourami's home clean and healthy.1 Furry Diary plan

Can a Sparkling Gourami live with others?

Yes, your Sparkling Gourami can live with other peaceful small fish like small cyprinids or loaches. Keep it as a pair or small group, but be aware that very small shrimp may be eaten.1

How long does a Sparkling Gourami live?

The lifespan of a Sparkling Gourami varies depending on care and environment. For specific information, ask a good breeder or an exotic-pet vet.

Can I handle a Sparkling Gourami?

It is best not to handle your Sparkling Gourami, as fish are delicate and handling can cause stress. If you need to move it, use a soft net and ask your vet for advice.
