Every living thing will grow and finally die. A cycle of life. Somewhere in between being young and old, is a stage known as maturity. Always the term refers to maturity in reproduction. Sexually matured.
For betta livida, after 3 months of age, the female will begin to show the egg spot or ovipositor. Its a tube that extends out of the body for releasing eggs during spawning activities. Then slowly the belly portion around the egg spot turns whiter. That would probably be the sign of accumulation of eggs. The female would be ready for breeding at this stage. Four months of age would be the starting point of being sexually matured. Young pairs will spawn, but there is a danger of them getting too stressful and finally die. I will put five months of age as being a safe age for successful breeding.
Age is tough to guess, unless its a fish that we breed. Wild caught fish is tough to guess. Purchased fish that comes with birth certificate is a rare occurrence. Then size would be a parameter worth looking at. But to measure the length of fish is quite a skill.
