Looking for a bit of advise. I have a 112 gallon 5 foot tank. Current stock list is couple clowns, few chromis, few cardnals, sailfin tang, mimic tang, bristletooth tang, hippo, and a wrasse. All get along great. Been all together for over a year. Was at my local pet store and they had a very small purple tang for sale. And by small I mean size of a quarter. Would I have any issues adding this fish? Wife really likes the purple tang. TIA
