There are many similarities these two species shared, both dwarf Gouramis and Guppies love to live in a tropical aquarium, and they can also cope in an extreme environment, this is why they are kept by adept aquarists though dwarf Gouramis are more aggressive compared to guppies that are calm.
Yes, Dwarf Gouramis and guppies can comfortably live together, but be aware that some large Dwarf Gouramis might eat the smaller guppies in your tank.
The conditions are outlined below.
The Size of the Tank: guppies thrive in at least ten-gallon size of water, the golden rule is one gallon of water must be provided for every one inch of fish, most adult guppy fish are within the size of 2 to 2.5 inches in length.
If this guideline is followed, your fish will have adequate space to swim in the aquarium, but 5 gallons is enough for two guppy fish, but the number of fish you want to keep will determine the size of your aquarium.
On the other way round, dwarf gourami comes in bigger sizes compared to guppies depending on the species, they are within the range of 1.5 to 40 inches in length though dwarf gouramis of 1.5 inches can be kept in a nano tank of about 5 gallons.
But you need 30 to 40 gallons if you want to stock gourami of 40 inches. Hiding spaces is essential in a tank, make provision for live plants if you want to keep these two species in an aquarium.

Gouramis and Guppies Suitable Water Parameters
Both species live in freshwater, but you need to get rid of chlorine in the tank before stocking fish in the tank, but the water must be hardwater.
Well has the best hardwater that is most accessible, if you need to use tapwater it should be boiled, the reason is to eradicate chlorine which is toxic to fish, but you can also use an unboiled water if you don’t have access to a boiled water.
But you need to pour the water in a container without covering it then leave it in the open for at least six hours after which you’re free to pour it in your aquarium.
The aquarium water temperature should be within 72-82 Farenheight or 22 to 88 degrees in celsius.
PH between 6.8 to 7.8 is ideal for both Gouramis and Guppies living in the same aquarium
8-12 dGH is the appropriate water hardness level for these species, while the ammonia, nitrate, and nitrite concentration should not exceed 0ppm.
Both species have the same eating pattern, feed on almost the same meal, and it is easy to know when they are sick because they are usually social during feeding. You can feed them with raw/flakes vegetables, frozen foods, spirulina, or any live foods meant for fish.
Please note, the feeding time should not exceed 120 seconds so that overfeeding will not occur, and the water will not be messed up due to high number of leftovers.
