Sigh, clownfish

[Jekyl]

So my clowns have never show an interest in my nem. Couple weeks ago due to a tank issue my nem split. Both seem to be doing OK now. They aren't fully extending anymore but opening and deflating daily. Now however my clowns are actually showing interest. They keep nudging one on the foot. They aren't biting, the nem isn't closing up from it. Is this something I should be worried about?
