Take it from someone who just battled a terrible Aiptasia infestation in the past few months. THe best product is Joe's Juice (sold at ***********.com). It kills the Aiptasia and if you only have two, they'll be gone before you know it. How do you only have 2 after 3 months? You sure it's Aiptaisa? My Aiptasia went from 1 (before I even know what Aiptaisa was to literally over 500 (at least) in the span of 1 month!!! I couldn't keep Peppermint Shrimp alive for god knows what reason, all my other inverts have thrived in my tank. In fact, I found two smaller peppermint shrimp being consumed by Aiptasia!!! So I finally took a risk got a Copperband (they're known to be rather finicky eaters) and luckily he took to the Aiptasia like you wouldn't believe. Today, about 1.5 months later, my tank has a couple tiny ones from time to time and if the Copperband doesn't get them, I juice them with Joe's Juice!
