I’m used to finding the odd aiptasia in my 90 gallon every month or so. I usually let it grow a little and then get rid of it with some aiptasia destroyer. I got them from the live rock that I used for this set-up as I did not cure the rock before putting it in the tank.

This is the first time I have seen one growing on anything but the rocks. I did not think they would grow on a skimmer pump, but that’s where I found one when I went to move a few things around in the sump.

At least this one will be easy to get rid of
