Giant Gourami Breeding
Giant Gouramis are mouthbrooders, meaning that the female incubates the eggs in her mouth until they hatch. When ready to breed, the male will build a bubble nest at the water’s surface. Once the nest is complete, the female will be introduced, and spawning will begin.
The female can lay up to 2000 eggs, which the male will then fertilize. Once the eggs are fertilized, the female will pick them up in her mouth and incubate them for about two weeks. The fry will be released once they are free-swimming and can fend for themselves.
Giant Gouramis are not difficult to breed, but it is best to leave them in their natural environment. If you breed them in captivity, ensure the tank is at least 50 Gallons and has plenty of hiding places.
The water should be clean and well-filtered, with a pH between 6.5 and 8.0. It is also essential to provide plenty of live food for the fry once they are released.

Giant Gourami Complete Care Guide
Giant Gouramis are easy to fish to care for and make good community fish. They are best kept in an aquarium of at least 150 gallons with other peaceful fish. The tank should have plenty of places to hide and swim.
Gouramis are omnivorous and will eat most prepared foods, including pellets and flakes. They also enjoy live and frozen foods such as bloodworms, brine shrimp, and daphnia. Feed them 2-3 times per day.
Gouramis are slow-moving fish and prefer to stay near the bottom of the tank. They can live for up to 10 years with proper care.
As long as Giant Gouramis have plenty of room in the aquarium to swim around and there are more live plants than artificial accessories, the gouramis will live a long and happy life.

Tank Size
The Giant Gourami is a large fish requiring a large tank. Fish keepers should keep adult fish in a tank that can hold at least 200 gallons of water, as more significance is always better.
Failing to provide Giant Gouramis with sufficient space will result in depressed, unhealthy fish that will not live long.
Water Parameters
Giant Gouramis are not fussy fish and will do well in various tank conditions. However, there are a few things that should be kept in mind to make sure they thrive.
Firstly, Giant Gouramis need a lot of space. As such, fish keepers should provide them with a tank that can hold at least 200 gallons of water or more. Failing to offer Giant Gouramis sufficient space will result in depressed, unhealthy fish that will not live long.

Secondly, Giant Gouramis are slow-moving fish and prefer to stay near the bottom of the tank. As such, live plants should be provided for them to hide in and around.
Thirdly, Giant Gouramis are tropical fish requiring warm water to thrive. An ideal temperature range for Giant Gouramis is between 68°-86°F, with a pH of 6.5-8.0.
Keeping the room temperature consistent with the tank temperature is crucial, as drastic temperature changes can harm or kill fish.
Filtration
When we talk about the filtration for Giant Gouramis, we discuss two types: mechanical and biological.
Mechanical filtration removes physical debris from the water, such as uneaten food, fish waste, and plant matter. This is typically done with a filter with a sponge or other media that captures the debris as water flows through it.
Also, check: Black Neon Tetra 101: Best Care Guide, Species Summary & All.
Biological filtration is the process of removing dissolved waste from the water using bacteria. These bacteria convert the trash into less harmful substances that the filter removes from the water.
We recommend using a canister filter with mechanical and biological filtration for a Giant Gourami tank. A canister filter will provide enough filtration for a Giant Gourami tank and ensure the water remains clean and clear.
Following are some commonly recommended filters for these fishes:
- Fluval FX6 Canister Filter
- Eheim Classic 2217 Canister Filter
- SunSun HW-304B 5-Stage External Canister Filter
