Is 72 degrees OK for a betta?
Is 72 degrees OK for a betta? In fact, they have a pretty narrow ideal temperature range – the most optimal being 78-80º F (s25. 5-26.5º C). Although betta fish can tolerate temperatures ranging between 72-86º F (22-30º C), if the water is outside of their ideal range, they’re just surviving — not thriving.
