I recon that probably helped but accustoming the file fish to eat Aiptasia, i like the idea of this method, however i dont have a quarantine tank at the moment looking to buy one in the future as they are really handy and especially introducing any new corals, something i have learnt as i gained more experience in this hobby and 100% it is pot luckI didn't realize so many people had filefish that won't eat aiptasia yet went for the corals.i wonder if mine ate it because I put aiptasia in the quarentine tank for him to chew down on before putting him in the main tank I have him over a year might be 2 yrs can't remember and he doesn't mess with my corals. But when I have my hand in the tank cleaning he likes to nip my hand once in a while. Dame his teeth hurt.. guess it luck of the draw..
