My three month old betta has been eating only one pellet (if at all) since Thursday night. Today she stayed in her faux plant most of the day. I can't see any outward signs of disease, fin rot, Ect.
She's in a 1 gal tank, and I had just changd her water Wednesday, the day before she started acting like this. Water was treatd as always. I dit her taknr on a large heating Pad that keeps it a consistent 72-74 degrees. She's now in a quarantine .5 gal tank. She's slightly more active, but still not interested in food.
She's had gravel in her tank for two weeks.... And I remember the last time I used gravel, when she was a fry, she became pale and not herself. Could gravel be the problem?
