I have had the big clown for 2 years and just added a juv pair about 2 weeks ago. One of the juv has paired up with the big one and the other one is hanging out around my powerhead. The nems have been in there for about a month.
Just a side note there was never any agression from any of the clowns toward each other or the other fish. One just paired up and the other one stayed away. Will they eventually go after the solo fish?
