little man! I'm sure he had an awsome life with you! 5 1/2 years is a long time 
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? 
. I hope your next one lives just as long!
Sweet Fish Friend
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
