I have to admit that I was skeptical about our purchase of 15 nudibranches after 2 months went by without any sign of them. But around the 8 week mark we started seeing them and their handiwork. Now two reasonable sized areas of the tank are clear of aiptasia, and we can easily see the nudi's at work without trying very hard. We've also spotted 3 different sets of eggs, in their circular pattern. So they seem to be thriving and slowly but surely cleaning up our tank.
