Thanks for that information Can you tell us which was the particular one is the pair you got Please ORA - Filefish?I'm a SOLD Filefish person. I tried Aiptasia X (it made my nems extremely unhappy), I tried kalk, I tried super glue & even tried lazer method. All of those methods did nothing but irritate aiptasia, and aiptasia is a form of anemone - you upset it it splits/multiplies. IE: I would fry aiptasia w/lazer - next day there was twice as many. FINALLY I added a pair of ORA raised filefish and within a week my aiptasia vanished. According to folks at ORA - Filefish are shy and usually eat at night - so it might take up to two weeks before they devour aiptasia.
