Sooooo trueI bought like 11-13 i forgot, most being medium size with a few large ones to eat the large aiptasia, for my 120. Within the first day or so, the rock i put them on was aiptasia free, it's been about a month now and ive seen a good reduction, i check on them sometimes if i get up or am up at 1am to see if they are still alive. They can get pretty big.
They really do work, it just sucks they are so expensive. But at the price of corals in my tank, its worth it to me
If you do it, you and your tank will thank yourself later once the sting stops hurting in the wallet LOL
