I have a male 9 month old KSB who has been so far healthy, eating well, non-aggressive. Today when I took him out to feed, I noticed that there were a handful of dark black splotches on his belly, only a little bigger than pinpricks. They are raised and he didn't used to have them. I only noticed when he wrapped the fuzzy, so I didn't want to disturb him too much during or after the meal. Could these be bits of sand stuck under his scales, or parasites? Please Help!
