I have had my tank for 3 months and have recently had an outbreak of Aiptasia after adding some live rock to my sump about three weeks ago. I bought a File Fish two weeks ago, on advice from LFS, to counter the problem but appears the File fish enjoys the other food more and is not tucking into the Aiptasia. I introduced a second File Fish this weekend as the outbreak is getting extensive. Not sure if I should stop feeding all the fish in the tank for a couple of days to force the File Fish to eat the Aiptasia. The other fish in the 100 gallon tank is as follows:
4 x Clowns
3 x Chromis
2 x Blenny
1x Sandperch
