That was one very lucky betta. A long time to have him hugs to you, you need to post on this forum you must know what you are doing....have you got another one?
Wow, 5 1/2 years, you must have been great friends. I know how it feels, I've also got a betta that is a little over five years old. He doesn't move around much anymore and he's not as colorful, but he's still a great pet . I hope your next one lives just as long!
So sorry for your loss. He must have loved you a lot--to have been able to have such a long life! But I send you hugs and hugs to help soothe the ache of loss! (I recently lost one, too)
And what a cutie he was--he looks like he had some personality.
WHat a great life you gave that fish!! He is in what i like to think of as fish heaven, where the bloodworms are endless and there is no bad water quality and plenty of room Sorry, that is a long time and i am sure it hurt to lose him. Good luck
