After some careful look into my nano cube i noticed in several places where i could see possible aiptasia growth in different areas of my rocks. I know they are harmful to corals and i have a few frags in my cube. I was considering aiptasia x as a cure for my problem but a true newbie i have never used the stuff. Is it successful, or which way would be better to eradicate this pest?
Be very careful. Aiptasia-X, Joe's juice, etc CAN work well if you do everything correctly. If you don't do it exactly right, you will create a massive infestation of aiptasia. I learned this the hard way.
All types of cures work to some degree. Peppermint shrimps can work, but some do and some not (I have had both types). Matted (aiptasia-eating) filefish work very well if you get a good one, but can also nibble on corals if you don't feed them well after the aiptasia are gone. Copper banded or Klein's butterfly should work, if you find healthy ones.
For a nanocube, I would pull the rock out and blast the aiptasia with a torch of some sort (blowtorch, kitchen torch or torch cigar lighter that you can get very cheaply on
Amazon). You can also plug the hole where it is/was with epoxy or cyanoacrylate gel. I suppose that hot water would also work, but haven't tried this.
For me, the filefish was the best choice. It eradicated the aiptasia in my nanocube and went on to do the same in my 75g. I saw it nipping on acros occasionally but this stopped when I started feeding mysis daily.
Good luck,
