I have had my Betta for 19 months now. I use to have 2 Betta in seperate bowls and they use to flare at each other all day. They both were very healthy fish. Unfortunately, my niece cause one to die and now my baby 'Blue'; that's his name; he just lies there all day and barely moves. I don't know if he is depressed. Can Bettas get depressed? Is he missing the other fish? And if so, what can I do to help him? I noticed that his fins are really long and thick. He seems to have a hard time moving them. I recently purchased another Betta in hopes of him starting to flare up and swim around more; which he does, but not for long periods of time. What can I do to fix this?
