Almost 3 years ago I inherited a veil tale betta from a teenager who bought him at major chain pet store in a cup. She was visiting a friend for the summer and without thinking she couldnāt of course take him home on the plane. Iāve done my best to give him a good life these past 3 years. Heās getting old, his blue color is getting dark and his fins look thin, he sleeps a lot and has not built a bubble nest in about a year and half. I moved him from a 5 gallon to a 3 gallon hoping it would help him get to the top more often. But he continues to sleep on the bottom and not swim like he used to. This past week Iāve found him stuck to the filter 2 times. Iāve turned it off. Now should I move him to a small tank or bowl since Iām not going to have the filter? When or should I consider putting him down? How do I do that? Never was a pet person but Iāve grown attached to Rocky and want to do right by him. It stresses him a lot when I use the net, I just hate to have to catch him to move him to clean his tank.
