True perc Clowns

[aha24]

I added 2 perc clowns about a month ago and one died after a day today I picked up a small one to see if they will pair. the larger one that was in the tank shakes its tail end real fast every now and then when the new one is near is this good or bad the larger does not seem to be aggressive towards it or attacking it.

Mine are paired and the male does this also. I don't speak clown but I think it's a good thing.
