Been dealing with a bacterial bloom since two astraea snails decided to fall off the glass and I didn’t catch them until a day later as I was out of town. So this morning I completed a 3g water change on my 4g tank. While the water was low took all my zoas out and did and iodine dip and as I was pull them out to rinse I found this. Pretty sure it’s a zoa spider but want to make sure. Going to keep a close eye out for others. Inspected all frags and that is the only one I saw.
