What an awesome tank! 8D

I know you said you are nervous about adding anything in the tank with him. I have seen a lot people have no gravel at the bottom for easy cleaning and just having fake plant and a hiding spot. Maybe try that idea out for a bit so it will be easier to clean and take care of?

did you use soap to clean the decor the last time your betta died? I know soap can kill any fish.

I'm sorry for your loss. =( It's hard to loose an animal, even a fish.
