What do gourami eggs look like? Gourami eggs are extremely small and look like transparent air bubbles. The female will spawn eggs when the male hugs and bends her belly upward to the foam nest he built. After spawning, these tiny looking eggs will usually flow up and stick to the nest. Some eggs might stick to the plants or filter. Knowing that is very important for fishkeepers who want to know about gourami thoroughly. Watch this video to look at the whole gourami breeding process and how eggs look like:
How gourami eggs look like in a community or a spawning fish tank
There are multiple gourami species, and overall sexual dimorphism may be easily observed as:
- Males are larger and thinner than females
- Male colors are brighter
- Male fins are longer than
- Male dorsal fin is larger and longer
- Female dorsal fin is a bit rounded
All these are the most accurate signs for determining the sex of gourami fish.
You do not have to be a competent or an experienced breeder or make a significant financial investment for breeding gourami fish. Gourami can be bred in a normal aquarium as in a 10-20 gallon or 30 to 70 liters spawning fish tank separate from the main community aquarium. Still, it is better to hustle a bit and get a new tank.
For breeding gourami in a community aquarium, floating plants like riccia or hornwort are required. Gourami eggs are very small and sticky, and if they don’t stick to any plant, decoration, or nest, they will be eaten by other fish. Another critical factor of gourami eggs surviving is the lack of strong currents from filters.
The following water parameters are recommended for successful gourami breeding:
- Water temperature between 75 to 81 Fahrenheit or 24 and 26 degrees Celsius,
- Water hardness between 4 and 10,
- Water pH between 5.8 and 6.8.
Both at the bottom and top of the fish tank, there should be plenty of plants available for the female to hide. The pair is lavishly fed for around 1 to 2 weeks, ideally with live food, to stimulate spawning. Gourami mating games look fantastic. Gourami colors shift to a more bright one. The male maintains the integrity of the foam nest in the same way that a father protects his. It takes the male around three days to make a foam nest.
The spawning of gouramis can begin as soon as the nest has been constructed. Once the male has successfully enticed the female into his nest, he squeezes her and fertilizes eggs. The typical spawning phase lasts between 3 and 4 hours on average with repeated cycles. You may speed up the spawning process by adding one-third of distilled water to the spawning tank and keeping the temperature at 84 Farenheight or 29 degrees Celsius.
Depending on the species, the average number of eggs produced by a female can be a couple hundred to couple thousand. After the spawning ends, the fish begin to swim in different directions. The female will seek protection after spawning ends, while the male will care for and protect the nest. To prevent the female from being attacked by the male or causing harm to the nest by consuming eggs from novice parents, they both should be placed in a different fish tank. Incubation time for gurami eggs ranges between 24 and 48 hours. The temperature of the aquarium water has a significant impact on the development of the eggs.
After 2-3 days, the eggs reach the fry stage and are able to swim independently. Again, they are so small that both females and males will simply eat them without notice and transfer them away. Especially the male as he doesn’t eat anything during this period. Don’t forget to have an air pump. Yes, gourami is one fish that needs no oxygen, but an air pump is essential for new fry until the labyrinth organ is developed at the age of one month.
Gourami fry has to be fed with “fine powder” ciliates or other special fry food. It is critical to ensure that food is consumed and that any leftovers are removed as soon as possible.
Here are some rules for forming a pair of gourami ready for spawning. First and foremost, the creation of a couple should occur spontaneously in an aquarium with a whole school. Simply look at all the gourami and notice which ones are constantly close to each other. Secondly, because gourami prefer clean water do water changes more often. Thirdly, it’s best to give them a break from stress by covering the aquarium’s front with paper, cardboard, or a towel for a few hours, especially during the spawning stage. Fourth and last, guramis can spawn in aquariums without the nest in some cases. The caviar then floats on the water’s surface or sticks to plants. The fry can successfully hatch tris way. Just make sure nobody eats them.
