Hello everyone, thought i'd introduce myself. my name is Adam and i live in Florida. i've never had fish before in my life and i recently bought a 55 gallon fish tank and one look at the Tiger Oscars and i knew i had to get one. Im planning on just getting one because they get so big i am concerned about the width of the tank i bought it says its 13 inches but i measured it and its only 12 inches. im worried that when it becomes full grown it wont be able to turn around

. but anywho i have yet to set up my tank and i know i have to cycle it before i put anything in there, im pretty much looking for advice from experienced fish owners
