Mcoskers being a jerk

[shpobble]

Hi

I added a small (1.5inches) female mcoskers (although appears to be colouring up and likely transitioning now) and a similar sized female pintail to my 90l qt tank at the weekend, and as of yesterday the mcoskers keeps shooting after the pintail, havent seen any nipping and pintail doesnt seem too concerned, but dont want this to get out of control - I wanted to add another fairy wrasse (lineatus or rubrimarginatus tbd), and have a fat ornate on reserve - will adding these disperse the 'aggression' or make it worse? Mcoskers pays no attention to the pink streaked or possum, or nocturne goby, just the fairy...and i thought they were meant to be a peaceful species?

If neither is being forced into hiding and there's no damage occurring to either, I'd let it ride out. They'll likely find tolerance.

will adding these disperse the 'aggression' or make it worse?

Should disperse it.

My mccosker was getting harrassed by my yellowtail. He would hide alittle but come out to eat and get chased back. 4 days later they are swimming together. My pintail is the boss tho

Put a mirror against the side of the tank to disperse the aggression for a couple of days.
Then take it away!
