OK, I decided to pick them off the Astrea Snails manually. I found 12 Astreas and moved them to my QT tank. Some of them had about 20 pyramids on them and others only a couple. Probably picked out about 100.
My question is, is there anything else they would feed off of? I have about 10 Cerith Snails, 1 Queen Conch and 2 Nerite Snails left in the display. I don't believe they feed off of corals, but I have Muchrooms, Zoas, Yellow Polyps, Finger Leather, Blastos, Frogspawns, Torch, Hammer, Galaxeas, Monti. Digi, Pocllioporo and an Acro.
I believe I got out all of the hosts, so in that case about how long is the life cycle? And how about any eggs? How long should I leave the snails out for?
