Im checking here so i dont get in trouble with the tang police, recently i bought a 3ft by 2ft by 2ft tank and currently have a 20gallon so quite the upgrade, i currently have a pair of clowns and bangai cardinals as well as a midas blenny and royal gramma, i am thinking about a flame angel but what do you think about tangs and whether there are any smaller ones that would fit as i think most need at least 4ft? Thanks for any help. By the way i have more rock but it is currently in my old tank.
