I have two 100 gallon and one 55 gallon tank.. 2 Oscars (7 inches) in the first tank.. one severum (7 inches) and one frontosa (8 inches) in the second 100.. and one flower horn (8 inches) in the 55.. and I have a 9 inch leporinus which chases and nips all the fishes.. so no matter which tank I put him in, he dominates.. doesn't even spare the fh.. has anyone had a similar experience with lepos? I don't want to get rid of this guy because he's been with me for more than a year.
