Pearl Gourami Care: Tank Size, Diet & Tankmates
Pearl gourami care guide: 30 gallon tank, 77 to 82F water, why this peaceful labyrinth fish needs surface plants, diet, tankmates, lifespan, and breeding.
The pearl gourami (Trichopodus leerii) is widely considered one of the most beautiful and peaceful gouramis in the hobby. A fine lacework of pearly spots covers its body, and breeding males develop a striking orange-red throat and breast. Reaching about 4 to 5 inches, it is a larger, more graceful relative of the dwarf gourami, and it shines as a calm centerpiece in a planted community of 30 gallons or more.
Like all gouramis it is a labyrinth fish that breathes air at the surface, and it appreciates a dimly lit, well-planted tank where its shy nature can relax. Here is how to keep one at its best.

Tank setup
Plan for at least 30 gallons, with a long footprint so these mid-to-upper level swimmers have room to glide. That space also lets you keep a calm community or a small gourami group without crowding. To match the tank to your stocking plan, begin with our minimum tank size calculator, then verify the full load with the stocking calculator.
Planted, dim, and gentle
Pearl gouramis are slightly timid, so a planted tank with subdued lighting brings out their confidence and color. Floating plants such as red root floaters, salvinia, and frogbit are ideal: they soften the light, provide security, and give a breeding male anchor points for a bubble nest. Keep open gaps at the surface so the fish can breathe air. Gentle flow suits them, so a baffled hang-on-back or canister filter works nicely, and a heater near 3 to 5 watts per gallon holds steady warmth.
Water parameters
Keep pearl gouramis at 77 to 82F, with a flexible pH of 6.0 to 8.0 and soft to moderately hard water. Never add them to an uncycled tank: complete a full fishless nitrogen cycle, usually 4 to 6 weeks, so ammonia and nitrite read zero first. Regular partial water changes keep nitrate low and the fish relaxed. For step-by-step cycling and testing, see our water and care guides.
Diet
Pearl gouramis are easygoing omnivores. A balanced routine looks like this:
- Use a quality tropical flake or small pellet as the daily staple.
- Rotate in a second flake for variety.
- Offer frozen or live bloodworms, brine shrimp, and daphnia a few times a week.
- Let them graze plants, where they also pick off tiny pests like hydra.
Feed small amounts once or twice daily, only what they clear in a couple of minutes, to keep water quality high.
Tankmates
Thanks to their calm temperament, pearl gouramis mix well with other peaceful, similarly sized fish: larger tetras, rasboras, rainbowfish, corydoras, cherry barbs, and bristlenose plecos all make good companions. Avoid fin-nippers and boisterous or aggressive species that would intimidate them. Keep a single male per tank, or one male with a few females, to minimize territorial displays during breeding.
Health
Pearl gouramis are hardy when kept properly. Most health issues, such as ich, fin rot, or fungal patches, trace back to stress or poor water quality, so stable temperatures and low nitrate are your best preventives. Quarantine new fish when you can, and avoid sudden parameter swings. For a clearly sick fish, consult a local fish store or an aquatic vet rather than dosing blindly.
Breeding
Pearl gouramis are bubble-nest breeders and are quite achievable for an attentive keeper. A male intensifies in color, builds a floating nest often woven into floating plants, and entices the female to spawn beneath it. He then guards the nest and fry. For best results, use a separate, gently filtered tank with lots of surface cover and slightly warmer water, and remove the female after spawning and the male once the fry are free-swimming. Plan grow-out space ahead and recheck capacity with the stocking calculator.
Is a pearl gourami right for you?
If you have a 30 gallon or larger planted community and want an elegant, peaceful centerpiece, the pearl gourami is a superb choice. Give it dim lighting, floating plants, gentle flow, and calm tankmates, and it will reward you with shimmering color and graceful behavior. Before setup, confirm your real water volume with the aquarium volume calculator so heater sizing, dosing, and stocking are based on accurate gallons.

Frequently Asked Questions
How big do pearl gouramis get and what size tank do they need?
Pearl gouramis reach about 4 to 5 inches, larger than dwarf gouramis, so they need at least a 30 gallon tank with a long footprint. The extra length gives them room to swim and lets a calm group spread out. If you plan to keep a small group or a busy community, size up further and confirm the load with our stocking calculator before adding fish.
Are pearl gouramis peaceful?
Yes, pearl gouramis are among the most peaceful gouramis and make excellent community fish. Males can show mild territoriality toward one another, especially during breeding, but serious aggression is uncommon in a well-planted tank with enough space. You can keep one male with several females, or a single specimen, alongside calm community species without much fuss.
Do pearl gouramis need floating plants?
They strongly benefit from them. Pearl gouramis are a bit shy and feel most secure with subdued lighting and cover at the surface. Floating plants such as red root floaters, salvinia, and frogbit dim the light, give the fish a sense of safety, and provide anchor points if a male builds a bubble nest. Leave open gaps so this labyrinth fish can always reach the surface to breathe air.
What do pearl gouramis eat?
Pearl gouramis are omnivores. Use a quality tropical flake or small pellet as the staple and add frozen or live foods like bloodworms, brine shrimp, and daphnia several times a week. They also nibble algae and small organisms among plants, and interestingly will eat hydra and small pest organisms. Feed small portions once or twice daily, only what they finish in a couple of minutes.
What are good tankmates for pearl gouramis?
Their calm nature pairs well with other peaceful, similarly sized fish: larger tetras, rasboras, rainbowfish, corydoras, peaceful barbs like cherry barbs, and bristlenose plecos all work. Avoid fin-nippers and very boisterous or aggressive species that would stress them. Keep just one male per tank if you want to avoid territorial displays, and check the combined bioload with our stocking calculator.
How long do pearl gouramis live?
With good care, pearl gouramis commonly live 4 to 5 years, and some reach a bit longer in a stable, well-maintained tank. Longevity comes down to the basics: a fully cycled aquarium, warm and stable temperatures, low nitrate from regular water changes, a varied diet, and low stress. A calm tank with floating cover and gentle flow helps them thrive.
