My female dumbo betta has lost her appetite for about a week.
I looked at her, but there are no signs of velvet and any other disease. her fin looks completely fine either. she's completely healthy in appearance.
she lives in 5 gallon tank, together with 2 other female betta (i think it's okay since they are still 2 months old) but the other two looks fine, and they are really active.
yesterday i try to do 50% water change, because i was afraid she poisoned by ammonia. but nothing change.
even worse: she gets very weak, and just lying in the bottom of the tank. she doesn't swim much, and just do it to take a breath in the surface.
here's a pic of her
