Hello, I recently impulse bought a 10 gallon fishtank (no fish yet) and was wondering what and how many fish I could put in there with a male betta being the "centerpiece". Does it matter what kind or variety of betta I should get? Do they have different characteristics besides color? What fish would leave the male betta alone and not get mauled by the betta? I was thinking tetras and sucker fish and snails but I am not expert so please help if you can and sorry for making this so long.
