For your aiptasia woes, you really have two options since Aiptasia products are off the plan for you. Peppermint shrimp and a filefish. I would never recommend peppermints to anyone and I wont do that here either. So you can go with a filefish, but they sometimes get a taste for corals so you will have to watch that. The only other option would be a copperband butterfly. That comes with its own set of difficulties as well. My best option for you would be buying some berghia nudibranchs. They arent cheap but they will only eat aiptasia, hence they will die off when its all gone, but they will breed in your tank and local reefers that have aiptasia will gladly take them off of your hands.
