The question being, how can you tell the age of a Betta?
To answer your question, No bettas tail and fins do not have anything to do with telling the ages of them. There is actually NO way possible to tell the betta fish's age unless you have records of the Spawn itself or can ask the breeder. This mostly implies to bettas in LPS's (Local Pet Stores). On AB you will be able to ask the breeder how old the fish is and they will tell you. You see I bought my fish from a breeder and they were hatched by 8/28.
Though the short finned bettas that you see on AB is most likely a Female betta or a HMPK (HalfmoonPlakat) or PKDT(PlakatDoubletail) or PK (Plakat) plakats are what the short finned bettas are called. There are tons of tail types and the short ones have PK in them and thats what makes the short fins.
For example. If I buy a pure HMPK pair and breed them, they will produce HMPK's which have short fins and they will stay like that. They are just hatched as short finned bettas and have nothing to do with age.
I hope I answered your question. Enjoy the Forum!
