My betta that I have had for almost 3 years (3 years in like 2 weeks) died today.. just found him on the bottom of his tank, no signs of any disease prior just he sat on the bottom quite frequently and would come up in a hurry for food but had been that way for months. Fins all in good shape and no signs on body, he was just a normal petsmart betta and iv read thats about the right lifespan for them give or take a year :-/ bummer, Im tempted now to buy a fancier betta lol
