Scrambles the Death Dealer
-Also lovingly referred to as Scramble-man. If you don't get the reference, it's from Metalocalypse when Nathan Explosion was asked to name a hurricane. He called it Scrambles the Death Dealer, and this name just stuck to my betta! The last picture is a picture taken right before he died.
I'm sure there's another thread to post this in (this is my first post) but I'd like to figure out the most likely cause of his death so I can avoid the same mistake in the future. He started acting a little off and I didn't think to do anything about it until it was probably too late. He seemed weak and tired during his last few weeks, hanging out at the bottom of the tank, but would have sudden outbursts where he would almost skip across the surface of his tank. Possibly lack of oxygen? But, I keep the surface of the water accessible. Anyway, he stopped noticing when I put food in the tank and I had to start removing old food (which I have never had to do with him). As it got worse, his tail/body would curl up towards the surface of the water with his head pointed towards the bottom. I added Bettafix to his water and he died the next day. :(
