from the little research i've done, i've gathered that they can live around six years at most? someone correct me if i'm wrong!
Thank you!Sadly, more then not as of the last few years bettas in general have been living for only 1-3 years... but in the right environment, with the proper water changes it is possible to live up towards 7 years. But commonly, it's 3-5 in the average, well cared for betta.
