I come home this morning after buying 3 flowerhorns from FHcruiser. I put 1 in a divided 60 gallon, 1 in a divided 20 gallon, and the last in a 10 gallon thats half full as there is no lid. I decided to go out and buy a lid for the ten gallon and when I come back and look into the tank, the FH is gone. Behind the tank is the FH. When i picked it up there was blood on the towel that I put under the tank. I try to resuscitate him for an hour and just got nothing. Lesson learn always assume they will jump.
