ph levels for betta fish
Shares & Saves. Save. The proper pH for a betta (also called a Siamese fighting fish) is somewhere between 6.8 and 7.2; however, maintaining a constant pH is more important that having the âproperâ pH. Betta can adapt to different pH levels, provided the changes are gradual.This is most especially important when changing the tank water.aving pH levels between between 6.8 and 7 is preferable, but those between 6 and 8 should not cause harm to your betta. The most important point about pH is to remember that the level is not as important as the constancy. Bettas can adapt to different pH levels, provided those levels change gradually.
