IME, never once, did putting an aggressor in a box have any effect on the aggression. The aggressor, when let out simply asserted themselves and their past position on the new comer.Walking away meaning in absence to come back and see fish shredded. A couple days is sufficient and I often state a few days, based on observations and fish after two days as advised was released and went back to it, confirming why you dont let them have at it.
We dont wait for fish to get pinned constantly to determine it’s a good time to remove it.
IMM, only time allows the “resetting” of a heirarchy and there are a number of other methods which can be employed in sequence to hopefully provide a “window” of opportunity to allow this to happen, without pulling any fish.
While I would not allow a fish to kill another, I do let them decide, what the ranking will be.
In my setup, the yellow is at the bottom of the tang hierarchy, which in this case, is the exact opposite.
Then again, that’s just my way of doing things as wrong as it may be.
