Gouramis range from tiny peat-swamp specialists to giant food fish that outgrow ordinary home aquariums. This guide to types of gourami fish covers 30 aquarium-relevant species and color forms, including peaceful community choices, territorial labyrinth fish, delicate blackwater species, and several giants.
The common name “gourami” is used broadly. Most species here belong to the labyrinth-fish family Osphronemidae, but kissing gourami belongs to a separate family and remains included because aquarium keepers universally recognize the name.
What Are the Main Types of Gourami Fish?
Popular beginner and intermediate choices include honey, pearl, thick-lipped, dwarf, three-spot, blue, gold, opaline, moonlight, sparkling, and croaking gouramis. Chocolate and licorice gouramis need specialist soft-water care. Kissing, giant, red-tail giant, snakeskin, and some combtails become too large or assertive for small community aquariums.

How Are These Types of Fish Classified?
| Group | Examples | Care pattern |
|---|---|---|
| Trichogaster | Dwarf, honey, thick-lipped, banded | Small bubble-nesters; generally suited to planted aquariums, with species-specific temperament. |
| Trichopodus | Pearl, three-spot, moonlight, snakeskin | Medium to large gouramis; three-spot forms can be assertive. |
| Sphaerichthys | Chocolate, samurai, crossband chocolate | Shy soft-water mouthbrooders for advanced keepers. |
| Trichopsis | Sparkling and croaking gouramis | Small sound-producing species suited to quiet planted tanks. |
| Parosphromenus | Licorice gouramis | Highly specialized peat-swamp fish needing very soft acidic water. |
| Large gouramis and relatives | Giant, red-tail giant, kissing, combtail | Need large aquariums and careful behavioral planning. |
Where Do These Fish Live?
Gouramis are native mainly to South and Southeast Asia. Habitats include rice fields, floodplains, canals, slow rivers, forest streams, peat swamps, ponds, and marshes. The group’s diversity explains why one universal water recipe is inappropriate: a hardy three-spot gourami and a licorice gourami come from very different environments.
How to Identify Different Types of Gourami Fish
- Body size: separate dwarf and sparkling species from moonlight, kissing, snakeskin, and giant gouramis.
- Pelvic feelers: many familiar gouramis have thread-like pelvic fins used to explore their surroundings.
- Pattern: pearl spots, three-spot markings, chocolate bars, or croaking-gourami iridescence are useful clues.
- Mouth shape: kissing gourami has thick protrusible lips; pikeheads have a long predatory snout.
- Color morph versus species: blue, gold, opaline, and platinum gouramis are forms of the three-spot gourami.
- Behavior and habitat: shy blackwater fish and bold open-water gouramis require very different setups.
Aquarium Care Notes
- Research the exact species before buying; common names alone can hide major differences in adult size.
- Cycle the aquarium fully and keep ammonia and nitrite at zero.
- Use a lid because gouramis surface to breathe and some jump.
- Provide plants, floating cover, wood, and line-of-sight breaks.
- Do not crowd multiple territorial males in a small aquarium.
- Feed a varied omnivorous diet, with appropriately sized foods for the species.
- Avoid strong surface turbulence for bubble-nesting species while still maintaining adequate filtration.
- Quarantine new fish and observe for appetite, breathing, sores, and abnormal swimming.
Safety, Sustainability, and Conservation Notes
Do not release gouramis into natural waterways. Some species have become invasive outside their native range, while peat-swamp specialists are threatened by habitat loss and poorly documented trade. Prefer captive-bred stock, especially for licorice, chocolate, and other sensitive species. Never buy a giant species without a realistic adult housing plan.
Fun Facts About Gourami Fish
- Gouramis can gulp atmospheric air using a labyrinth organ.
- Many species build bubble nests, while some chocolate gouramis mouthbrood.
- Croaking and sparkling gouramis can make audible sounds.
- A kissing gourami’s “kiss” is commonly a dominance display.
- Blue, gold, opaline, and platinum gouramis are color forms of one species.
- Giant gouramis can become true monster fish.
- Licorice gouramis are adapted to extremely soft peat-swamp water.
- Thread-like pelvic fins help many gouramis touch and investigate objects.
- Male coloration can intensify during courtship and territorial displays.
- Labyrinth breathing supplements gill respiration; it does not replace clean, oxygenated water.
Final Thoughts on Types of Gourami Fish
The right types of gourami fish depend on aquarium size, water chemistry, experience, and tankmate behavior. Honey, pearl, thick-lipped, and sparkling gouramis are often gentler choices, while three-spot morphs and paradise fish can be territorial. Chocolate and licorice gouramis belong in specialized soft-water setups, and giant species require exceptionally large long-term housing.
Frequently Asked Questions
1. What is a gourami fish?
A gourami is a freshwater labyrinth fish, usually from Asia, that can breathe atmospheric air as well as use its gills.
2. How many gourami species are there?
The broader gourami family contains well over one hundred species, although only a smaller number are common in aquariums.
3. Which gourami is best for beginners?
Honey, pearl, thick-lipped, and carefully sourced dwarf gouramis are common options, but tank size and local stock quality matter.
4. Which gourami is the most peaceful?
Honey and pearl gouramis are often among the gentler common species, although individuals vary.
5. Are gouramis aggressive?
Some are peaceful, while others are territorial or predatory. Males can become more aggressive during breeding.
6. Can two male gouramis live together?
Sometimes in a large, structured tank, but many species may fight. Research the exact species and provide visual barriers.
7. Can different gourami species live together?
It is possible in spacious aquariums, but similar body shape, territorial behavior, and water needs can create conflict.
8. Do gouramis need to be kept in pairs?
No universal rule applies. Some do well singly, others in carefully balanced groups, and breeding pairs may become territorial.
9. Do gouramis need a heater?
Most common aquarium gouramis are tropical and need stable warm water, though some paradise fish tolerate cooler conditions.
10. Do gouramis need a lid?
Yes. A lid reduces jumping and helps maintain warm humid air above the surface.
11. Why do gouramis go to the surface?
They regularly gulp air with their labyrinth organ. Constant gasping may still indicate poor water quality or illness.
12. Do gouramis need an air pump?
Not always, but filtration and oxygenation remain important. Surface breathing does not eliminate the need for good water quality.
13. What do gouramis eat?
Most aquarium species are omnivores that accept quality prepared food plus frozen or live foods; specialists may need small live foods.
14. Can gouramis live with bettas?
Usually this is risky because both are territorial labyrinth fish with similar body signals.
15. Can gouramis live with guppies?
Some peaceful gouramis can, but large or aggressive species may chase guppies and long fins may attract nipping.
16. Can gouramis live with shrimp?
Small shrimp and shrimplets may be eaten, especially by larger gouramis.
17. How long do gouramis live?
Lifespan varies greatly by species, genetics, size, and care; many common species can live for several years.
18. How large do gouramis get?
Sparkling gouramis stay tiny, while giant gouramis become extremely large. Always check the scientific name.
19. What is the difference between blue, gold, and opaline gourami?
They are color morphs of the three-spot gourami, Trichopodus trichopterus.
20. What are the three spots on a three-spot gourami?
Two dark body spots plus the eye are traditionally counted as three.
21. Why do kissing gouramis kiss?
The behavior is usually a test of strength or dominance rather than affection.
22. Are dwarf gouramis hardy?
They can be, but some mass-produced lines have serious health issues. Source carefully and quarantine.
23. What is dwarf gourami disease?
The term commonly refers to a viral disease associated with some dwarf-gourami stocks. There is no reliable home cure, so prevention and sourcing matter.
24. Are honey gouramis the same as gold gouramis?
No. Honey gourami is a small species; gold gourami is a color morph of the larger three-spot gourami.
25. Why is my gourami hiding?
New surroundings, bright light, aggressive tankmates, sparse cover, illness, or unsuitable water may cause hiding.
26. Why is my gourami chasing other fish?
It may be defending territory, breeding, competing for food, or reacting to crowding.
27. Do gouramis build bubble nests?
Many do, especially males in Trichogaster, Trichopodus, and related groups, but not every species uses the same breeding strategy.
28. What is a chocolate gourami?
It is a small, shy soft-water gourami that usually needs warm, acidic, very clean conditions.
29. Why are licorice gouramis difficult?
They often require extremely soft acidic water, quiet surroundings, small live foods, and careful species identification.
30. Can gouramis live in hard water?
Some hardy species adapt, while chocolate and licorice gouramis generally do poorly in hard alkaline water.
31. How often should I change gourami tank water?
Perform regular partial changes based on stocking, feeding, filtration, and test results while avoiding sudden parameter swings.
32. Why are my gourami’s feelers touching other fish?
The thread-like pelvic fins are sensory structures used to explore the environment and investigate tankmates.
33. Can gouramis jump?
Yes. Use a secure lid and cover equipment gaps.
34. Should I buy a giant gourami for a small tank?
No. Giant gouramis require very large long-term housing and should not be purchased as temporary small-tank fish.
35. Can aquarium gouramis be released outdoors?
No. Release can spread invasive species and disease and may be illegal.
