How do you know how old
your betta is??
bettas were horses, we'd look at their teeth. If bettas were birds,
we'd look at the skin texture on their legs. If bettas were people,
we'd ask them, listen to their answer, deduct 5 to 10 years and have
a good idea of their age. LOL
But bettas are not so simple. If you were to bring me a betta today and ask me to estimate its age, how would I go about it?
I would look for the following clues:
In closing, it is very hard to estimate with any kind of certainty, the age of the bettas from unknown provenance. That is why once again I must stress that if you are serious at all about your hobby, you purchase your stock from an established, experienced breeder only. Such breeder will be able to tell you how old the betta is, not because he/she can guesstimates, but because he/she KNOWS, since he/she keeps track of spawn's birth month and knows all their spawns/bettas intimately.
