My 10 gallon is almost donít cycling after 2 weeks and should be done soon. Is it best to add Master Betta to the tank after I already have introduced his future tank mates or is it better to add him first?
It's whatever way you want to do it. I always put other fish in first and then put in the Betta so that way he didn't feel like it was more of just his territory and attacked other fish. That's just my opinion though.
