I seem to have several ribbons of cerinth eggs layed on rock work and on my glass. It looks like an explosion of egg laying within the last few days. The first egg mass appeared on my live rock 2-3 weeks ago. I left these on the rock unprotected. It takes approximately 9 days for the hatch. My search for baby ceriths was fruitless. Maybe it was their size and they blended into the rock work. On tues. of last week another egg mass was layed on my front glass. Knowing the possibilites of scavengers eating them I devised a protecting of sort. The location of the eggs made it easy to bend a large fish net over the top lip of my tank and sourround the eggs. On the ninth day I discovered hundreds of small oblong almost invisable to the eye ceriths on the glass. I don't know if this increased their survival rate once leaving the enclosure or not. Only time will tell. As of today I have several egg masses layed on my rock work...maybe to late for protecting them. My next project is to create a small flexible net or enclosure made of bridal viel that could be formed to sorround the egg masses and increase their chances for survival. Just my thoughts..anyone with their experiences with snails and survival rates?

I get free swimming larvae from the Florida Ceriths but they always die a day into it, I should try again with some of this phyto.	breeding stock Posts: 377 Group: Members Member #69 Joined: November 22, 2008

I am trying neriths in a culture tank with no predators. I get lots of eggs on the acrylic but I have yet to see free swimming larvae. Dang it! Good Luck, Bob. Sounds like you are on the right track. An easy protection from large predators is one of those plastic cups that strawberries come in, you know the green ones? They are really easy to place over an area, water can flow in but fish cannot.

So far the net and the glass in front is covered with the usual algae we clean off the glass. I'm observing several of the babies moving away from the original cluster and some of them staying in the general area. Are they eating the algae off the glass? I can't get focused enough with my magnifying glass to get a good view of them. Do they really become free swimming? I have read lots of posts in my research and there are certain species that at least to my knowledge are not free swimming larvae. Some hobbiests write about seeing hundreds of offspring moving on their glass and eventually see them in the sandbeds. Maybe the species I have do not have swimming larvae.	breeding stock Posts: 137 Group: Members Member #84 Joined: December 29, 2008 Name Bob Kripfgans

I wonder if you could get some of them in an isolated area and see if they grow. Maybe they are not babies but little spp of their own. I tend to like the thought that some do not have a larval stage I really wonder if larvae could stay in the column of many of the coral heavy tank yet lots of people have them reproduce.	breeding stock Posts: 377 Group: Members Member #69 Joined: November 22, 2008

I think they must not have a larvae stage. If you are seeing them as tiny duplicates of their parents, it appears they have no larval stage. Sweet! But, I wonder if their predators would be large hungry amphopods?	Seahorse Whisperer Posts: 3,047 Group: Admin Member #1 Joined: June 28, 2008

Bob, the only time I have had tiny snails in my tank that survive is when I'm feeding my tank phyto once a week. The class Suzy and I are taking is all about raising stuff like this. But they say the only way to have real success and not just luck is to raise them in a separate tank where there are no predators.	stormy, stormy nights Posts: 2,362 Group: Admin Member #4 Joined: June 29, 2008

Eek! I have some! I am so sorry, we need to hook up. I work all day Mon & Weds and have little piddly things to do the other days. Pick a day not Mon or Wed, and I will tell you what time I can meet you? You do want Tetraselmis, the best alga on the planet, right?

You could just order some paste from BSD and you'd have it in a day. Their shipping is like $5. Just make sure they don't put any glycerin in it.	stormy, stormy nights Posts: 2,362 Group: Admin Member #4 Joined: June 29, 2008
