I'll try to get some more detailed pics this next weekend, work is keeping me busy this week. Looking at one of the juveniles in the fuge, from the bottom the foot and everything else looks exactly like the rest of my trochus.
I'm as skeptical as you Travis, it's unusual for banded trochus to actually breed in a tank with a skimmer and everything else. I'm not sure yet what is different in my tank/sump that allows them to survive. I'll definately keep an eye out for more in the future though, as it seems there isn't much for them to eat in the sump and all the empty shells may have been due to lack of food. The ones that seemed to have survived were living in my skimmer, which has had a problem in that once I added a light to my fuge, the light spill over to the skimmer causes it to grow a film of algae and lots of coraline as well. They probably found enough food in there, as 2 of the 3 surviving that I found were in the skimmer body. The other mystery is that it seems there are multiple generations from the big size difference between the largest I found and the smallest. The smallest was in the photos, and was pretty small, the largest was a live one and it's probably just under the size of a dime. I doubt that size variation would have been from one brood. Now that I know to look I'll keep a close eye out for juveniles, and transfer them to either my frag tank, or the fuge where there is more to eat. It would be really cool if they kept breeding, considering I only have a few adults in my tank now.
