After much self conflict and arguing with myself. I just can't divide my betta's home for another male. I think there is only room for one in my life, and thats Goku. I took out the divider to clean up a little and let him roam free and he just seemed so happy, and the tank looks better without the crappy dividers and the tank has a sort of "aquascape" effect going on that I want to build off of to make him a happier fish.
I might make this into a community tank with some oto's and tetras, and if I decide to divide the tank in the future, I want to do it right and make my own divider out of plexiglass and tank silicone, and do a java moss wall between them.
I know I know
betta fever does weird things to people.
I know he'll be so much happier than with dividers and enemies at his sides, and the tank has more decoration options.
