Fisheyes are little isolated spots that repel paint when it is being applied. These are caused by surface contamination, which stems from poor surface preparation. Reapplying paint in that spot will not remedy the issue. Oil, grease, wax, water, amine blush, or any other dirt can be considered surface contaminants.
If possible, try and isolate what type of surface contamination may be present. Either remove the wet paint and perform the surface preparation over with greater care, or allow it to cure and fix the issue. Once cured, the coating should be sanded back around the or removed, and the surface preparation should be performed with much greater attention to detail.
