Ok so my friend's betta fish seems unusally unactive and seems sick to me, so i decided to ask for help.
His name is Bob and he used to be active swimming around and so bright in colors, but now he just stays in a corner doesn't eat and his color is dull and he doesn't flare no matter what!
I am really scared because he was the one who inspired me to get a betta fish and he was with my friend for almost a year now and their anniversary is in March! I just don't want him to be sick on his anniversary in a month! Beacuse he's my betta too, I really love him that much.
