im kinda still new to the hobby. now i have a 40gal. long and was wondering what would be a good investment on fish to stock my tank with? i dont have the tank ready to go yet, still tring to decide on what to put in it. any help or opinions would be a nice help. i have no preference on malawi,tang,SA,CA. i just want to make sure the tank is going to be set up right for whatever goes into it. thanks in advance!
