Care at a glance
Species-specific aquarium care
- Tank: At least 24 in long and 12 in front to back for one adult (adults commonly reach about 1.5 in / 3.85 cm; the largest recorded was 3.1 in).
- Water: Freshwater.
- Temperature: 72–82°F (range recorded for this species).
- pH: 6–8.
- Hardness: 5–19 dGH.
- Layout: Lives on or near the bottom: floor space and hiding places matter more than height.
- Diet: FishBase classes it as a carnivore.
Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.
Care guide
Species care notes
- Tank: a base of at least 24 × 12 in (roughly 14 US gallons); space needed is rated “modest tank”.
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 72–82 °F, pH 5–7.5, 1–15 dGH.
- Behaviour: temperament peaceful; in a pair; suited to a community tank.
- Difficulty: Beginner (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “This species fares best in a well-planted, shady aquarium with plenty of surface cover in the form of tall stem plants, floating varieties, or tropical lilies.”
- Diet: “Stomach analyses of wild fish have demonstrated them to prey on an assortment of aquatic and terrestrial invertebrates.”
- Tankmates: “This species is peaceful unless breeding.”

Gouramis and labyrinth fish
Applies to most species in this group. Habitat: Warm, still, vegetated waters. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- Planted, calm tanks with floating plants; they breathe air at the surface, so leave a gap under the lid.
Diet
- Food acceptance is species-specific. Parosphromenus deissneri needs tiny live invertebrate foods and commonly refuses dried foods; a pellet/flake staple cannot cover every labyrinth fish.
Health watch
- Males are territorial; dwarf gourami iridovirus.
Understanding the animal
About this animal
About this animal
It is native to still waters in Southeast Asia such as Thailand, Borneo and parts of Java island, but due to the aquarium trade, the fish has spread to other parts of Southeast Asia (like East Malaysia) and to other parts of the world. As the common name suggests, this species is capable of producing a "croaking" noise using its pectoral fins.

| Where it lives | Lives in freshwater, in rivers and streams, lakes, mangroves. Stays near the bottom. Occur in shallow sluggish or standing-water habitats with a lot of vegetation. Common throughout the middle and lower Mekong. |
| Water it lives in | Freshwater, 72–82 °F (22–28 °C), pH 6–8, hardness 5–19 dH. |
| Climate | Tropical climate. |
| Behavior to plan for | Breeding: nesters. |
What this means for care
- Keep water within its wild range, 72–82 °F.
Native climate (measured)
Native climate (measured)
| Warm-season highs | about 93°F (up to 97°F in the hottest sampled areas) |
| Cool-season lows | about 65°F (down to 55°F in the coldest sampled areas) |
| Average temperature | 76–82°F across sampled records |
| Relative humidity | 72–79% on average (driest month about 65%) |
| Rainfall | about 1676 mm a year, with strong wet and dry seasons |
Measured at 261 wild occurrence records sampled against WorldClim 2.1 climate data (1970–2000 averages). Air conditions in the range are ecological context, not enclosure settings: microhabitats such as burrows, leaf litter or basking rocks can be cooler, warmer or more humid.

| Overview | The croaking gourami (Trichopsis vittata) is a species of freshwater labyrinth fish of the gourami family Osphronemidae. It is native to still waters in Southeast Asia such as Thailand, Borneo and parts of Java island, but due to the aquarium trade, the fish has spread to other parts of Southeast Asia (like East Malaysia) and to other parts of the world. As the common name suggests, this species is capable of producing a "croaking" noise using its pectoral fins. — Wikipedia (community-edited) |
| Where it lives | Home ranges Population dynamics Growth parameters Max. ages / sizes Length-weight rel. Length-frequencies Mass conversion Recruitment Abundance Life cycle Reproduction Maturity Maturity/Gills rel. — FishBase |
| Wild diet | In the wild, the croaking gourami is mostly insectivorous, feeding on insects and insect larvae. However, other food types, such as zooplankton, crustaceans, shrimp meat and plant matter, are eaten as well. — Wikipedia (community-edited) |
| Behavior | As the common name suggests, croaking gouramis are capable of producing an audible grunting or chirping noise, accomplished through the use of specialized adaptations of their pectoral fins. These noises are produced by both sexes during breeding displays and during the establishment of dominance hierarchies among males. — Wikipedia (community-edited) |
| Reproduction | Like many other gouramis, the male croaking gourami is a bubblenest builder, creating a small nest from air bubbles and mucus under a leaf. The water level should be reduced to 20 cm during spawning, circulation kept minimal, and the temperature should be approximately 28 C. Spawning occurs under the nest, with the female responding to the male's dance by rolling over, followed by the typical gourami embrace. — Wikipedia (community-edited) |
| Appearance and size | The croaking gourami reaches an average size of about 5 cm, though some individuals can grow as long as 6 or 7. Coloration is highly variable, ranging from pale brown and green to dark purple with black or red spots on the fins. 2 to 4 brown or black stripes or rows of spots are present on the flanks. Median fins have a thin iridescent blue coloration on their edges, and the iris is bright blue or purple. — Wikipedia (community-edited) |
| Biology | Obligate air-breathing; Occur in shallow sluggish or standing-water habitats with a lot of vegetation. Common throughout the middle and lower Mekong. Found in flooded fields in the middle Mekong (Ref 12975). — FishBase |
