That explains why it never touched aiptasia yet. That sucks. Feel LFS made a mistake, they knew i was fighting aiptasia but I only ask for a filefish and they had one in their back stock. I assume they knew i was getting it for aiptasia. This is a different picture when I changed color some
Could be a Monacanthus ciliatus, fringed filefish; the same thing just happened to me. Many times wild caught filefish are just automatically classified as an aiptasia eating filefish.
