I am so sorry to hear of the loss of your beautiful betta Patriot
. I am sure you gave him a good life and he did live to quite a reasonable age for a betta so at least he lived out his whole life span..... many poor bettas are lucky to survive a few weeks because of the misconception associated with the conditions in which people believe these fish can survive. I am sure Patriot would thank you for giving him a good home and being a carng owner.
Maybe it is too soon for you to be thinking about this but do you think you will get another betta? Please I would love to see a photo of Partiot if you have one and if you get a new betta would love to see it too.
