Are these bites?

[gugpuccio]

Hi guys I've had this acro for years now. The mother colony is doing fine, with nice purple coloration and growth, but this frag is almost identical to 2 years ago. I've always noticed some holes on the tissue but some friends always told me they were normal polyps.
No other acro in the tank has them. The mother colony has them but less severe it seems.
Can you help me? Could it be bites?
Thanks!

Thanks everyone, I will keep an eye on it, but I doubt it is spawning. It's been like this for months... could these be normal polyps not on the coralyte?
