sorry to hear that moe.... now i am also afraid f putting my fish into their new tank 210gal that is currently cycling..... it just su*** when you become attatched to ur fish and then u mess up and they die on you.
with a new tank I always buy a fish that looks cool but doesn't cost much and put them in before I put my nice ones in.... after testing the water of course.... you never want to kill a fish on purpose...
