I've had two baby crested geckos for a while now, set up in a bioactive enclosure with sprngtails, a fogger, cork bark and live plants. Recently when I've been putting their food (repashy) into their tank I've noticed these small black mites in the repashy. The two cresties are in perfectly good health but I'm just wondering whether these mites are a risk and how I could get rid of them
