Any danger in adding more Kribs to an established male in a tank?

[NicknClair]

Have a very settled and beautiful male Krib in my larger tank and was thinking of adding more. Will this affect the male, whom has been on his own for the last 3months? Am I better off getting him into a quarantine tank with the new ones, then put them all In at the same time. Or shall I just leave be?

I would rearrange the whole tank to make them reestablish territory's because they will fight if not. Ive had two breeding pairs in a 55 and it was always a constant battle.

After you QT the other kribs you need to remove the established male, totally rearrange the tank and plants, add the new kribs, then re-add the established male. What this often does it trick the old fish into thinking it's in a new tank where it has no established territory. This often works but sometimes it doesn't so be sure to have a plan if you have problems.
