They’ve been extensively launched outdoors their native vary, such because of the Philippines, India, Sulawesi, and southwestern Trinidad.
These fish stay in marshes, swamps, canals, and lowland wetlands. They migrate throughout the flood season from everlasting water our bodies to flooded areas, corresponding to seasonally flooded forests within the center and decrease the Mekong.
Through the dry season, they return to those everlasting water our bodies. These fish feed on zooplankton, crustaceans, and bug larvae. The male builds a bubble nest for the eggs, which he protects aggressively.
Within the aquarium
The three-spot gourami is a hardy fish. They are often housed with quite a lot of tank mates of comparable measurement and temperament. Whereas males could be territorial with one another, they turn into timid round different, extra aggressive fish.
Male gouramis are identified to be very aggressive; they might even be fin nippers and usually might hassle different fish within the tank.
They usually present aggression towards species with lengthy, flowing fins corresponding to male guppies, goldfish, and bettas, as a result of they show lengthy tails and vibrant colors, presenting competitors for impressing feminine gourami. Feminine gourami generally hassles different fish, however, they often maintain to themselves.
Although aquarists are usually informed to not home a number of gouramis collectively, three spot gouramis which have been introduced up collectively in pairs (often females, particularly if they’re siblings) and which have steady personalities, can efficiently cohabit with one another, supplied there may be sufficient room to swim.
This varies primarily based on particular person personalities, however, it has been achieved by aquarists.
In such conditions, usually, one might assume an extra dominant position and develop bigger, whereas often teasing or playfully chasing across the smaller submissive fish, however, each will usually be tolerant and cooperative towards one another.
The three-spot gourami is an omnivore and requires each algae-based and meaty meal.

Nevertheless, some females might have a dorsal fin so long as the males. When able to breed, the male builds a bubble nest after which begins to entice the feminine by swimming forwards and backward, flaring his fins and elevating his tail.
The feminine might lay as much as 800 eggs. After spawning, the females usually are eliminated to a separate aquarium because the male might turn into aggressive towards her. The male protects the eggs and fry, however, usually is eliminated after they turn into free-swimming.
After hatching, frequent water adjustments, particularly throughout the third week, are used to make sure the well being of the fry, as that is when the labyrinth organ is creating.
Blue gouramis are one of many hardiest of the gourami household. Their desire is for thickly vegetated waters of any kind, as their pure habitat contains ditches, canals, ponds, swamps, rivers, and lakes.
Blue gouramis tolerate a variety of temperatures and will not be demanding by way of water circumstances. Nevertheless, they like smooth, barely acidic water throughout the breeding season.
Although they do have a labyrinth organ and might breathe air if completely obligatory, you will need to maintain the tank well-filtered; you may as well add air stones to enhance oxygenation.
You could wish to present a darker substrate just because it makes such a reasonable distinction towards the colors of the blue gourami.
Three spot gourami tank measurement
The Blue Gourami will swim in all elements of the tank. When younger they will simply be housed in a 15 – 20-gallon aquarium, however, adults will want at the very least 35 gallons or extra.
It’s fascinating to maintain the tank in a room with temperature as shut as possible to the tank water to forestall damaging the labyrinth organ.
Three spot gourami are identified to alter coloration (their black spots will fade) when underneath excessive stress or when they aren’t stored underneath good circumstances.
Wholesome fish have two vivid black spots on either side of their bodies, however these fade with age.
Selectively bred varieties mostly obtainable within the aquarium commerce are opaline (or opal) (with a marbled sample), platinum (or silver) (whitish), blue, golden (or gold) (xanthochromistic), and lavender (or amethyst) (the results of crossing a blue and golden, having a purple coloration).
