So last month I got filefish and few days ago got a Kleins butterfly fish to deal with this persistant aiptasia issue. I have lost patience for these aiptasia that yesterday i build a vacumm jose with a 1/4" end and did my best to suck them out, I was not successful but it felt good lol. Than i dosed them with sodium hydroxide. My hope was the file fish would start to see them as food when they became distressed. So far they are nipping at the rock but have not seen them do anything to the aiptasia yet.
