Gourami sexing isn't the same as establishing the gender of a livebearing fish. It's crucial to figure out which are male and which are female if you wish to them. This article will show you how to identify Gourami gender and how they reproduce.
Male and Female Gouramis
Male Gouramis are typically smaller and have a thinner overall girth than females. In comparison to men, females have a rounder belly. The dorsal (top) fin, on the other hand, is the most noticeable variation between males and females. The female's dorsal fin is small and rounded, but the male's dorsal fin is larger and pointed. Keep in mind that baby fish are more difficult to distinguish from adults. The fins of juvenile fish are not fully grown, and they have not yet reached adult size.
There are many species of Gouramis and some can be a challenge to breed, while others, like the Blue Gourami , readily breed in aquariums. To stimulate breeding, you'll need to perform two things. The first step is to set up an appropriate tank, and the second is to get the fish ready to reproduce. Most tanks will not please the male enough to let him create a nest of air bubbles at the surface to encourage the female to lay eggs, so you can't just put a pair of Blue Gourami into a tank and expect them to couple up and breed like livebearers would. Although the male is the dominant partner, it is the female that makes the breeding decision.
Feed Gouramis a diverse diet that includes flake food, algae wafers or spirulina flakes, freeze-dried bloodworms, tubifex, and brine shrimp to prepare them for breeding. For a few days, you may also offer them live meals and fresh vegetables like chopped lettuce or cucumber. The male grows significantly more vivid and darker than the female during breeding season. In peak breeding form, a female Blue Gourami will resemble a golf ball. She's chubby and stuffed with eggs. You'll know she's ready when you see this; there's no doubt about it. The male will not create a bubble nest if he does not like the surroundings. There will be no place for the female to lay her eggs if there is no nest. So, the next step is to prepare a tank that will be suitable for the male.
The Best Tank Environment for Breeding Gourami
The tank should be roughly 20 gallons long and filled with older water and floating plants. The tank temperature should be between 74 and 79 degrees Fahrenheit, and the pH should be neutral to slightly acidic. Gouramis love soft water, and a well-kept aquarium is usually a benefit.
Because the male prefers calm water to build his nest in, the tank should not include an air stone or filter. He will not attempt to build a nest if the water is too turbulent. Gouramis are labyrinth fish that can survive in low-oxygen environments by rising to the surface to breathe.
It is very important to have loose branches and leaves of aquatic plants floating on the surface of the water as these are used by the male in building his bubble nest.
How Gouramis Breed
The fundamental mating ritual is the male constructing a bubble nest for the chosen female and chasing her about, often aggressively, until she submits and inspects the nest. If she is impressed with his efforts and agrees to lay her eggs in his home, she will display herself in a way that indicates to the male that she is prepared to do so.
The male will then roughly grasp the female and wrap himself around her to assist her in expulsion of the eggs into the nest. Any eggs that do not make it into the bubble nest will be collected by the male and blown back into the nest in a bubble. You should remove the female once they have produced and let the male to care for the eggs.
If the female is not removed, and she is not a competent hider, the male may murder her while guarding the nest's eggs and, subsequently, the fry (baby fish). You should also remove the male as the eggs begin to hatch, since if something irritates him, he may consume them all. In the wild, his role is done after the fry hatch; they scatter to consume infusoria, and he moves on to find another female to mate with. When breeding gouramis, have a tiny amount of food on hand to feed the fry after they exit the bubble nest; young brine shrimp (frozen is acceptable), microworms, or finely crushed flake food will suffice.
