At the time of breeding, they need to be healthy and to raise the fry to a healthy adult fish, you need to follow diet and tank and water arrangements mentioned below.

Diet of Paradise Gourami Fish

They live on an omnivorous diet, and you must feed them high protein foods. A combination of plant materials along with insect protein will be ideal for them. Live and frozen foods along with dry foods and flakes will also be nutritious for them. When it is extremely hungry, it will clean up the algae of your aquarium too. You can feed them:

  • Algae wafers and flakes like Fluval Bug Bites, Zoo Med Spirulina
  • Pellets ( HIKARI Micro Pellets, API Fish Food Pellets)
  • Freeze-dried veggies and fruits
  • Freeze-dried worms
  • Daphnia
  • Small aquatic insects
  • Dead flies
  • Bloodworm
  • Tubefix Worm
  • Mosquito Larvae
  • Small insects (Live or Frozen)
  • Brine Shrimp
  • White Worms

In their natural habitat, they consume Planktonic Invertebrates, and Zoobenthos and their tendency of hunting on the prey can be seen whenever you will feed them live foods. At the time of breeding, feed the females first as they will not intake any food at the time of holding the eggs.

You can feed this fish twice a day and make sure each time your fish can finish the food within two minutes.

Tank Requirements of Paradise Gourami Fish

In order to raise a healthy fish, along with a nutritious diet, you need to take care of the tank as well. Keep this in mind that you are taking out the fish out of its natural habitat, so you need to replicate its natural habitat in your aquarium.

Tank Size

A 20-gallon tank is a minimum requirement for them. If you are planning to keep a small fish in a 5-Gallon Tank, it will not be a problem at the initial stage, but in its adulthood, an adequate place will be required.

They are very sporty, and they swim almost all day, so a small tank will not be enough for them. If you are planning to keep them with others, go for a 30-gallon tank. For a single male one, you can opt for a 20-gallon tank.

Tank Lid

A tight lid for the tank is mandatory as they are avid jumpers.


Sand will help you to replicate the natural habitat of them. It will help the fish to dig hiding places too. Small rocks and caves will also be good for them as well.

Aquatic Plants

Aquatic plants will also help the fish to hide from their enemies. However, they are known for eating these plants too. You can select hardy plants such as Hornwort for this purpose.


Do not cover the aquarium surface with plants. Keep a little place so that the Paradise Gourami Fish can continue to swim up to surface and take oxygen directly from air using labyrinth organ.


It is very adjustable by nature. They can endure almost all tough conditions, but this may reduce their lifespan. So, you must keep the aquarium clean. Install the filters to remove the uneaten food and fish wastes. If you don’t want filters, you need to do manual cleaning each week.

Pumps are not required as high or low current are unnecessary for Gouramis. They live in no current areas, and they can inhale oxygen from the air.


Using LED lights will be the best and cost-effective here. Also, this light will create a great ambience in the aquarium.  

Well, that’s about the aquarium adjustments, now have a look at the water parameters.

Paradise Gourami Fish has the least demands regarding water adjustments; they can survive in the least or no water management, but it can make them unhealthy. You need to make the minimum adjustments in the aquarium water so that your fish face the least problem to survive. Take a look.

pH Level

Just like any other freshwater fish, pH level of the tank water needs to be 5.8 to 8.


5 – 30 dGH is the ideal water hardness for them.

Nitrate Level

Nitrate level has to be zero or extremely low to keep the fish healthy.

Cleaning Methods

Use of soap or chemicals is restricted, but you can use store-bought solutions.  

Replacement Procedure

Partial water change (25%) is required each week, and it will help them to cope up with the changes.

Compatibility of Paradise Gourami Fish

Due to the aggressive nature, it is recommended not to keep two male ones in a tank as they will hurt each other.  One male and one or more female ones will be compatible. Females are also more compatible and less aggressive than males.

For their aggression, choosing tank mates is a bit difficult for them and aquarists prefer to keep them alone. They physically attack the small and same-sized fish and damage their fins, but they don’t mess with large ones. Take a look at their suitable and unsuitable tank mates.

Suitable Tank Mates of Paradise Gourami Fish

  • Dwarf Gouramis
  • Bristlenose Pleco
  • Large Synodontis Catfish

  • Fancy Goldfish
  • Angelfish
  • Discus Fish
  • Neon Tetra
  • Guppies
  • Bettas
  • Snails
  • Crabs

Breeding of Paradise Gourami Fish

Before breeding, keep the male and female in good condition separately and feed them with healthy live and frozen foods in less quantity several times a day. Females will appear plump as they will start filling out with eggs after feeding.

At this stage, they should be met in a breeding tank with adequate aquatic plants. They are also the bubble nest builders, and males blow bubbles that go up to the surface and form a nest by joining more bubbles. A durable nest attracts the females to lay eggs where the eggs will be secured.

After forming the nest, the males will start courting the females and embrace the females so that the eggs can be fertilized when the females release them.  It may take a few minutes to a few hours to lay all the eggs which go up directly in the bubble nest. After spawning is done, remove the female from the tank as males become extremely aggressive to them. Males will take care of the nest and eggs. Alternatively, you can use a 10-gallon breeding tank for hatching.

Eggs may take 1-4 days to hatch. After hatching, remove the male fish as they tend to eat the fries. You can feed baby Brine Shrimps or micro worms to these hatched fries.
