well I just got home and found my powder blue dead in my QT and my hippo is laying on its side. idk if it was due to the cold or what, but I'm really ****ed!
Brando457 - Did you clean your QT from the last time you used it? Also are all your heaters and everything working on your QT? Sorry to hear your lost.
Bummer. The word "quarantine" is based on the Italian word for "forty" so take a clue from that. 55 gal is not very big for such active fish. Do you have some sort of filter media to treat amonia? Are you moving/aerating the water to keep oxygen levels up? Do you have adequate hiding places so the fish can feel secure when stressed?
