My betta fish that ive only had for 14 days used to swim around allot, was alert and was brightly colored. Now he has lost ALLOT of color and just sits and reacts to absolutely NOTHING!! He's in a fish bowl and this week i was going to get a 10 gallon with a heater and a light filter but im not sure if I should if hes just going to croak on me now.
I did clean his bowl hoping it would help to but its been about a day and nothing has changed! HELP!!!!!! PLEASE!!!!
