Using Mirror For Aggressive Tang

[PeterC99]

Added a Powder Brown Tang to my aquarium 4 months ago. At first he was very shy and chased by a Sohal Tang. Now the Powder Brown is the aggressor.

Put this mirror up yesterday and now he’s not bothering anyone. Wondering how long I should leave the mirror there?

Generally 2 weeks
In time, the Sohal will assume the role of aggressive- it’s their nature

Only took 15 minutes for my PBT

15 minutes for what - to stop the aggression towards the other tangs?

Yes, towards other fish. It was the first fish in the tank, and when I added a golden angel it tore it up. Did the mirror for 15 minutes and it hasn’t bothered a fish since.

I don’t get it. When the mirror gets removed and the fish no longer sees another fish like himself to be aggressive towards, does it just forget that there was another fish in the tank prior to the mirror that it just beat up? I guess fish aren’t the sharpest knives in the drawer.

I’ve used this trick when introducing new tangs to the tank. Took only 1-2 days till I was able to remove the mirror. I’m not sure that this will work because the two fish have already been introduced for some time
