Re: Breeding Journal, Species: Cerithium sp.

I took a small pipette aliquot from the bottom of my sieve to check today, and found several veligers amongst the little clusters of debris down there. I'm not sure if they are seeking out the debris for feeding reasons, or just coincidence. I'm still adding live phyto twice a day to keep the water in the sieve tinted. I believe this would be day 8 post hatch (veligers first observed on 9/18 from this egg cluster). Here are a couple of photos taken today, at 100x mag.

My periodic check of the debris on the bottom of the sieve turned up veligers again today (day 11 post hatch). In this (shaky) video clip, it looks like tiny eyespots are visible. They are still very tiny, this is 100x mag. lots of other little critters in the debris with them! https://www.youtube.com/watch?v=lYPpyoMXZdo

That's excellent!!! Mine are doing ok, but they probably need more algae. Crossing fingers!

I realized today that it's been about a week since I checked on the veligers, but no more to be found when I thoroughly examined the containers contents. I also took gentle scrapings from the side and bottom, but no settled snails either. I think next time I'll try a clear glass container, no sieve. Looks like 11 days will be my target to beat on the next batch.

I collected some eggs again, spawn 3/13/15, collected on 3/15/15. I just scraped the egg strand off the glass and put them in a little plastic container floating in my frag tank. The eggs hatched the next day, 3/16/15, with tons of veligers (and the water looks like a dense rotifer culture). I added some live tetraselmis and will see how long these make it. Since my last ones made it to 11 dph, I won't add many pics unless they pass that point. Here is an iPhone pic of the hatch showing the hundreds (thousands?) of veligers unmagnified on hatch day.

Well, I think I killed all of these by my own fault. Day before yesterday all was well, added some live t-iso to their little container. Yesterday the little container never got any attention, was left sealed all day & no phyto added (a large family gathering at my home). I just checked the container an hour ago, and could not see any veligers swimming. I checked a bit of the settled material and found tons of empty veliger shells and billions of ciliates feasting. At least now I know how to get a ciliate culture up & running!
