My betta fish just died probably old age, had him for a while. I was thinking of switching around my tanks. I currently have a 36 gallon with a dwarf powder blue gourami, cat fish, tetras and rasbora. I was thinking of putting the gourami, 3 cat fish and 3 rasboras in my 10 gallon the betta was in so I can add some new things to my community tank. Any qualms with this?
