Sparkling Gourami
Trichopsis pumila
Also known as: pygmy croaking gourami
A tiny 4 cm gourami with genuine sparkling spots and a croaking call at spawning. Needs a quiet planted tank with surface cover; male pairs fight.

Checked against several solid care sources that mostly agree. Numbers here are a careful starting point. Your tap water, tank size, and habits decide the rest. How we evaluate.
Best for: Planted nano tanks 40L or more with very small peaceful fish and floating plants or surface vegetation.
Avoid if: You keep boisterous active mid-water fish that outcompete for food or crowd the surface zone.
Common mistakeHousing two male sparkling gouramis in a nano because they looked tiny in the bag is how keepers invent a permanently excluded fish. Males fight for the surface; the loser stops eating. Keep a proper group with cover, or a single male centrepiece — not two males in a bare 20L.
Top things that go wrong
- Shrimp & snails. Cherry shrimp and other dwarfs can coexist with peaceful small fish; baby shrimp are food for almost anything that finds them.
What most shops don't tell you
- 1.Myth: sparkling gouramis are bulletproof nano community fish that thrash any roommate plan. Reality: they need calm surface access, micro-food, and honest male stocking — two males in a bare nano is a long feud over the film, not a peaceful school.
- 2.Buying one or two as nano accents. Sparkling gouramis croak and display only in a group of six or more.
- 3.Mixing with bigger gouramis in the same tank. The 4 cm fish hides at the back, never croaks, never breeds.
- 4.Males make an audible croaking or clicking sound during courtship. Clearly heard in a quiet room at night. Many first-time keepers mistake it for a failing pump or filter valve before realising the fish is the source.
About this species
Sparkling gouramis are 4 cm labyrinth fish that audibly croak. Heavily planted soft-water nano tanks with micro tank mates suit them best.

Example setups
Starting points only. Run the pair checker for every fish you add.
Rough 90L+ layout: one calm centrepiece, 8–12 small tetras/rasboras, 6–8 corydoras-type bottom fish — verify every name in the pair checker before buying.
Safer directions include: Chili Rasbora, Ember Tetra.

Behaviour and temperament
Sparkling gouramis are peaceful labyrinth fish that flare more at rival males than at calm tetras. They stay near plants and the surface film. A proper group with cover settles; two males in a short nano rewrite the tank into a chase loop.
What sets them off
- Sudden crowding
- Poor water quality
Fin nipping: Not a habitual fin-nipper; stressed or crowded individuals can still test fins.
Predation: Not a predator toward similarly sized community fish; fry and dwarf shrimp are still fair game for most species.
Territory: Not strongly territorial, but still needs room so its working space does not overlap the next fish.
Planted tanks: excellent — easy plant ideas
In the glass: typical and warning signs
- A group works the upper half among plants and may ‘sparkle’ or chirp at each other.
- Resting under floating cover between feeds is normal ownership, not illness.
- A male pinned from the surface is losing a fight — rearrange cover or remove a rival.
- Clamped fins under harsh surface current mean turn the filter down first.
- Male–male surface contests are the main risk inside the species.
- They rarely shred midwater tetras; they lose to bettas and boisterous barbs instead.
- Remove the losing male when appetite collapses or fins tear.
- Skip any tank that shares the surface with a male betta.
Fish behaviour can vary between individuals and tank setups. Always observe new fish closely after introduction.
Water, food, and grouping
Hardness
soft
Diet
omnivore
Sparkling gouramis take micro-pellets, crushed flake, and tiny frozen foods at the surface and midwater. Standard community flake often bypasses their small mouths. Feed small pinches they can finish near floating plants, and keep the surface calm enough that labyrinth breathers can rest without fighting filter blast.
Shrimp & snails
Cherry shrimp and other dwarfs can coexist with peaceful small fish; baby shrimp are food for almost anything that finds them.
Keep at least 6, bought at the same time.
- Hold 24 to 28 °C steadily on a real thermometer, not the dial on the heater.
- Aim for pH 5 to 7.5 and a hardness you can re-test in two weeks. A one-time strip in the shop car park is not a water test.
- Footprint: short wide tanks and tall narrow tanks fish differently for the same volume. Match the tank shape to the swim pattern, not just the litre count.
- Tank volume meets or exceeds 40L published minimum for adults.
- You can stock at least 6 individuals (group welfare).
- Heater can hold 24–28°C without cooking cooler-water tank mates.

Plan with tools
Check mates as pairs first, then add this fish in the tank builder for the full stocking.
Filtration & heating
A 40L minimum tank needs a filter rated for at least 160L/hr turnover and a heater to hold 24–28°C reliably.

How Fishori evaluates compatibility (same logic as pair and tank tools).
- Seriously Fish. Trichopsis pumila
Primary: aquarium size, water chemistry, behaviour, and compatibility (URL verified in upgrade script; recheck if site content changes).
- FishBase. Trichopsis pumila
Secondary: taxonomy, distribution, and maximum length in nature; cross-check with aquarium import lines and measured tank parameters.
- Wikipedia. Trichopsis pumila
Secondary: general species context; verify all husbandry numbers against a dedicated aquarium care sheet and your test kit, not a single table row.
Evidence notes
- The Seriously Fish profile for the binomial in this record was successfully reached as the primary aquarium reference.
- FishBase contributes natural-range size and habitat context. Translate those numbers through your heater, your water report, and your tank footprint before stocking.
- Wikipedia is only cited if the article URL returned OK. Use it for orientation, not as the only care sheet for an import.
- All compatibility text reflects typical hobby experience and the Fishori model. Individual fish, shop stress, and the order tank mates are added in can still defy a single-paragraph label.
Common questions about Sparkling Gourami
- How big do Sparkling Gourami get?
- Sparkling Gourami adults reach about 4 cm. Shop fish look smaller; stock for the adult length.
- What size tank does Sparkling Gourami need?
- 40L is the planning floor for adult swimming space and bioload. A 49L+ tank is the more comfortable long-term footprint. Length and depth matter as much as raw litres for active or territorial fish.
- Are Sparkling Gourami aggressive?
- Sparkling gouramis are peaceful labyrinth fish that flare more at rival males than at calm tetras. They stay near plants and the surface film. A proper group with cover settles; two males in a short nano rewrite the tank into a chase loop.
- What is the most common mistake with Sparkling Gourami?
- Housing two male sparkling gouramis in a nano because they looked tiny in the bag is how keepers invent a permanently excluded fish. Males fight for the surface; the loser stops eating. Keep a proper group with cover, or a single male centrepiece — not two males in a bare 20L.
- What fish can live with Sparkling Gourami?
- The Sparkling Gourami profile lists Chili Rasbora, Ember Tetra among its safer pairings (engine-checked GOOD). Angelfish, Betta, Celestial Pearl Danio, Pygmy Corydoras are conditional (CAUTION): workable only with the specific conditions on each pair page. Avoid Oscar (RISKY). Run the pair checker for your exact water and tank size before stocking.
