They enjoy having their own personal space, meaning that they should have enough foliage to hide in when they want to be alone. Often, plants or aquarium decorations can serve as good hiding places for betta fish.

Tips and Warnings. Related Articles. Article Summary. Method 1. Wait until characteristics begin to develop with age. Male and female Betta fish will look very similar when young. This is because their body has not yet developed to the point where sexual characteristics are manifested.
Before sexing your betta, either wait until you can see obvious male characteristics or wait about two months. Observe the size and shape of their fins. The dorsal and caudal fins will often droop due to their length. Female Betta fish will typically have shorter fins about as long as the Betta is tall or shorter. However, Plakat Betta Fish have short fins, so do not immediately assume that your betta is a female just because of shorter fins.
Female Betta's ventral fin may often resemble a hair comb. There are long-finned female Betta Fish that are sold by breeders.
Short fins may indicate female sex, but this characteristic should be combined with other evidence before sexing is conclusive. Note his or her colors. Females usually do not. Females from the petstore tend to have subdued or dull colors, especially in the body.
However, you can find colorful female betta fish from breeders. Bright, bold coloration in the body and fins is a good indication of a male Betta. Colors can change depending on the stress level of the fish. Female Bettas will be more colorful when stressed than non-stressed females. Look for the egg spot. This spot will resemble a grain of salt. It is located between the near the edge of the ventral fin near the head of the Betta.
Male bettas can develop a false egg spot, so using an egg spot to confirm sex is not the most accurate way. Finding this spot may be difficult with younger females whose sexual organs have not fully developed. As the fish ages and becomes larger, the ovipositor tube will become larger and easier to see.
If you are having trouble viewing the location of the spot, consider feeding or preparing to feed your fish. He or she will likely move to the top and angle himself or herself so you can more easily view the location.
