I have now lost 2 bettas in a week. I keep getting my water tested and it comes back perfect. I have 2.5 gallon tank (too big for a betta maybe?) just
have had no luck with these fish. My daugher was really upset we had to take her "sick" fish back to the pet store. I don't want one to die on her (she's 5) but not sure what I am doing wrong.. tank has been moved away from window to avoid any temp differences.. water is about 71 degrees.
Any thoughts as to what the problem is ? thanks
