A turn for the worse
I came home from work today and Cecil has taken a turn for the worse. His fins are more ragged than ever, his main tail fail has turned dark grey, his head is 75% white/silver, and he is barely able to move. He is floating more upside down than sideways and doesn't respond unless the tank is jostled. I feel so terrible every time I see him just obviously suffering beyond help day in and day out. I think its only a matter of days, if even, before he dies. Would it be the humane thing to do to put him out of his misery? If so, what should I do. . .
Thanks everyone for your help. :(
