Well, it's a darn good thing you took him back to the store. At least you didn't have to deal with him melting away and dying on you. I wish all reefers would make a pact to not buy them, because then they may just quit ordering them in only to watch them die. I know I'll never buy one again. It's to costly, and I feel so bad whenever something dies in my tank! Pick yourself out something new, and chalk it up to experience!
