Tank setup
One or a few thick-lipped gouramis need at least a 20-gallon long tank (76 L), about 30 in (75 cm) long. Plant it well and add floating plants, since this fish likes shade and cover. Keep the filter flow gentle. Cover the tank so the air above the water stays warm and humid for its surface breathing.

Water parameters
Aim for 23–27 °C (73–81 °F), pH 6.0–7.5 and soft to medium-hard water (about 4–12 dGH). Farm-bred fish handle most clean tap water. Do partial water changes every week and avoid sudden swings.

Feeding
It eats almost any food. Use a good flake or micro pellet as the base, then add frozen or live bloodworms, daphnia and brine shrimp several times a week. Some plant-based flake keeps the diet balanced.
Behavior
This is one of the gentlest gouramis. Fish raised together from a young age tend to get along for years, though males may spar if space is tight, so keep more females than males. Good tank mates include rasboras, danios, small peaceful barbs, tetras, loaches and corydoras. Avoid fin nippers that chew its thread-like feelers, and don't keep it with banded gouramis, because the two cross-breed.
Breeding
Males are larger and more colorful, with a pointed dorsal fin, while females are plainer and rounder. The male builds a bubble nest in a shallow, still, planted tank and guards the 500 or more eggs. Take the female out after spawning and the male once the fry swim. Feed the fry infusoria or liquid fry food first, then baby brine shrimp.
Tips from experienced keepers
- Buy a few young fish together and include more females than males for a calm group.
- Don't house it with banded gouramis. The two species hybridize.
- Keep fin nippers like tiger barbs away from its long, thread-like feelers.
- A gold form is sold as the sunset gourami. Check the scientific name, because honey gouramis are sold under that name too.
- Small shrimp such as cherry shrimp are likely to be eaten, so keep them in a separate tank.
Frequently asked questions
Are thick-lipped gouramis good community fish?
Yes. They are among the most peaceful gouramis and do well with small, calm fish like rasboras, tetras and corydoras.
How big do thick-lipped gouramis get?
About 3.5 inches (9 cm) when fully grown. That is larger than a honey gourami and a little larger than a dwarf gourami.
Can you keep two male thick-lipped gouramis together?
Often yes, in a well-planted tank of 30 gallons (114 L) or more. Males may spar, so give them cover and add females to spread out the attention.
