Best combination of tangs for a 5 foot 120 Gallon? I definitely want a Kole & a purple. I would also like a yellow and a convict or a Tomini. Is 4 tangs too many for that size of a tank? I know I can keep the Purple & Kole but would adding 1 or 2 more be okay? They would be the only large fish in the tank. If I could have 3/4 which would you recommend to accompany my purple & kole? Thanks & Tang Police - Please go easy hahah i’m asking so i get it right
