Tang and Trigger aggression QT

[Tnops]

Hey guys, I have a bristletooth tang and a male blue throat trigger (both 3-4 inches) in a 20 gallon QT for the first few days and they’ve been flaring at each other and also made physical contact. I have a 10 gallon that is already set up, should I put the trigger in the 10 gallon or try to separate the 20 gallon using egg crate?

Either will work. Might point towards issues once in the DT though.
