I sold mine then regretted it. The aiptasia is still in your tank and will come back with a vengeance once the filefish is gone. I ended up setting up a small 2nd tank for quarantining and growing macro. I keep the filefish there and bring him back for purges.
I know I really love this fish, I just love my rock nems more. I figure I can try to keep up with the aiptasia by hand now that I don’t see them. If not I’ll get another one for a while
