How to handle an aggressive sailfin?

[Detroit_306]

What can I do to help my lieutenant tang adjust to his new settings? It's been 24 hours and he's still nervous to be out and about with my sailfin, should I throw the sailfin in solitary for 72 hours? Or see if it persist?

how big is the tank, did u do anything to get them used to eachother (acclimation box, rescape, section tank off....???) or did you just toss it in and hope for the best?

Rolled the dice, its a 90 gallon, they are about 3.5-4" long

Both need a bigger tank. Salfin is established and claims that 90 for itself I am sure. You may get lucky with a rescape and lights out period for a day or two, but not a guaranteed fix.
