I recently bought a baby betta from PetCo about a month ago (before I learned that baby bettas aren't in the best health... but she's doing great anyway :) ) and because of it's small size, I just borrowed a 2 gallon bowl from a friend who wasn't using it anymore.
She's been getting bigger and bigger recently though, so I figured I should get a bigger tank before she's too big for what she's in now, so I picked up a 5.5 gallon tank today.
Other than rinsing out the tank and rinsing gravel and whatnot, is there anything special I should do to prepare the tank? Should I mix some of the water in her current bowl with the water that will be in the tank? Any tips and advice would be great!
