hello I don' t know what to do about my beta. We have had him 3.5 years and he was full grown when we got him so I don't know how old he is. I am sure that his problems are due to age but I don't know what I should do for him. I don't want him to suffer. He floats on his side at the top sometimes and does not move even if I move him- I tought he was dead but eventually he started swimming again. Now he is spending all day floating vertically with his mouth out of the water. His fins have a small amount of silver on them and his body is getting lighter in color.
