I have a betta that is over 2 years and is staying on the bottom of the bowl on his side. He occasionally swims to the top but quickly sinks to the bottom again. He is not eating and his color does not look good.
I have always kept him in the same bowl, changing 100% every week. I feed him pellets but he is not interested in the food at all. I do not have a heater for his bowl and although it is winter and the house is a little colder he has lived through a winter before.
I think he is dying and I don't know what to do for him. I work for a Hospice and know how to help people but feel so helpless with this little guy. Any suggestions?
