Female fishes can produce thousands of eggs in a single spawning. Monsoon season is usually when kissing gourami choose to breed. Kissing gourami may also move to flooded forests or shallow rivers before the spawning starts to take place. Females are the ones that initiates the mating, and the males often follow suit. Females get upside down to spawn the eggs, and the males release their sperm to fertilize the tiny eggs. Kissing gouramis have smaller eggs compared to other freshwater fishes and the eggs have a covering of oil droplets which helps them to float. The eggs rise and become attached to the available vegetation. It takes between one to two days for the eggs to hatch, and the parent kissing gouramis have no role in bringing up the fry. The young fishes start free swimming just after hatching. It takes about three years for kissing gouramis to reach sexual maturity.

Kissing Gourami Fun Facts

What do kissing gourami look like?

Kissing gouramis are known for having a flattened body with rounded caudal, dorsal, and anal fins. The dorsal fins of the fishes are longer than the anal fin. The fishes also have longer and rounded pectoral fins. The lateral line of the fish is divided into two parts, and they have about 43 to 48 scales running through it. Putting aside their large body, the most interesting part of this fish is their mouth. The protruded mouth of the kissing fish is lined with fine teeth. Artificial breeding has also led to the creation of the balloon kissing gourami, which has a smaller body with larger protruding lips.

The fish has ctenoid on their body and cycloid scales on their head. No particular sexual dimorphism is seen in the species, so it is often hard to tell the males and females apart. One kissing gourami interesting fact is that wild kissing fish have gray or green-colored skin, while ones bred for the aquarium have light pink colored skin. The fins of the pink, or balloon pink-colored fish, are almost transparent. However, there are some theories that believe the pink morph originated in Java. Both green kissing gourami and gray kissing gourami variants have a dark band running across their fins. The interesting look of kissing gourami is because of their intramandibular joint which is present between their jaw joint and other joints. The lips of a kisser fish help them to receive important nutrients while bottom-feeding.

What do they eat?

One of the most interesting aspects of kissing gourami fish is their diet. The fishes are omnivorous in nature, but most of their diet consists of plants. The kissing gesture of the fishes helps them to take nutrients from plants. Common kissing gourami food includes phytoplankton, zooplankton, benthic algae and aquatic plants. The fishes also have aquatic insects as a part of their diet. Kissing fishes are also known for bottom-feeding. As the fishes have gill rakers, the filtering helps the fish in extracting nutrients from the water.

In an aquarium where the fishes cannot have access to most of their usual food sources, they will eat live foods like bloodworms. Prepared fish food that has been specially made for gouramis can also work great. As a freshwater fish, kissing gouramis don't like clouded water so make sure to give an exact amount of food to avoid murky water. The fishes are also known to eat blanched vegetables like spinach, lettuce, or zucchini. If you cannot find live food, try giving your gourami frozen fish food to add a much-needed protein source to their food list. If possible, feed the fishes with some algae from time to time.

Are they aggressive?

Yes, kissing gourami are known to be semi-aggressive in nature. They are quite territorial in nature and can often pick a fight with their tank mates. The lovable kissing feature of the fish is often used to drive away other fishes that might be added to the aquarium. Hence, you need to be quite careful about adding tank mates that look like other gouramis as this can lead to aggressive behavior from kissing fishes.

Would they make a good pet?

Yes, kissing gouramis make an amazing aquarium fish and they are quite popular all around the world. The fish is mainly distributed in Asian countries where people love to keep kissing fish. Also, there is a misconception that this fish species needs to be kept in a pair. You can easily keep a single kissing gourami, but it should have a very large tank size. Kissing gourami care isn't that hard, but you would need to maintain the proper temperature range to keep this tropical fish happy. You should also be careful about choosing the tank mates for your pink kissing gourami. Loaches, barbs, and large tetras make great tank mates for kissing gourami. If you catch any fighting between the species or damage to any tail fin, it is better to separate the fishes.

Kidadl Advisory: All pets should only be bought from a reputable source. It is recommended that as a potential pet owner you carry out your own research prior to deciding on your pet of choice. Being a pet owner is very rewarding but it also involves commitment, time and money. Ensure that your pet choice complies with the legislation in your state and/or country. You must never take animals from the wild or disturb their habitat. Please check that the pet you are considering buying is not an endangered species, or listed on the CITES list, and has not been taken from the wild for the pet trade.

As a pet owner, you might be interested in kissing gourami fish mating. People often find it daunting, as breeding this species requires a big tank size. Both the fishes should have enough space to come up for air at the surface as well as enough space to swim. The perfect water temperature should be maintained to give them an opportunity to thrive. Make sure to install a good filter to keep the water clean and fresh. You should also place plants on the surface of the water to catch the eggs that are laid by the fish. With a proper environment for breeding and a large tank, kissing gourami females will soon start to spawn, and they may produce 1000 or more eggs. The eggs will slowly float to the surface of the water and attach themselves to the plants. You need to quickly collect the egg-filled plants from the surface and place them in a different tank. The eggs will hatch in around 24 to 48 hours to reveal free-swimming kissing gourami babies. The newly hatched fry will usually stay near plants to feed on infusoria. Brine shrimp also act as a good food source for the babies.

Did you know...

Gourami have a special type of organ, known as the labyrinth organ, that allows them to directly get oxygen from the air rather than from the water like other fishes.

Java ferns and Java moss work well in the aquarium habitat of kissing gouramis.

As a freshwater fish, kissing gourami may get fungal infections, so you may need to closely monitor their scales for any potential disease. If any anomaly is seen, remove their other tank mates to stop the disease from spreading.

Kissing fish: why do they kiss?

The fishes don't actually kiss. Gourami kissing provides the fish with an ability to suck on their food. The fish also uses their kissing mouths as a way to be semi-aggressive towards other fishes. As a territorial fish, kissing gourami can be a little daunting to other fishes or even fellow kissing gouramis.
