well the will lay all kinds of differnt colors the genectics you are looking for , can be found on applesnail.net I visit thier often to find ids of some of my snails .
I have had EVERYONE ASKING ABOUT MY SECRET HATCHING ' LOL
well as you see, its NOT a secret , mine just seem to hatch REALLY fast when I do this , as some have metioned above ...................
10 gallon tank , calcium pills are added every 2 weeks , they est veggies *( love cucumbers, zuchini is a fav , and leaf lettace ) I also feed flakes, shrimp pellets , & algea wafers as well

I leave the water lone pretty low, atleast 4-5 " low ~ (for huge clutches and where the water will not toutch the clutches . usually after I do a water change with cold water, theb add real veggies ^^ look above, I leave the fod in overnight with lights out , usually in breeding mode I will get 2 clutches atleast every 2 days for about off & on 2-3 weeks !!! . right now I am in waiting , no clutches atm .. I still have all differnt sized babies that I havent sold, waiting to see all my differnt colors .. !!! ~~ NOW ~ clutch ~~ I leave it on for 24 -48 hrs , then I take a playing card, or razorbade and slide from the bottom of the clutch up, this usually makes it fall off into my hands , it is ok if it gets in tank , or falls in water, just GET IT OUT > then I put in a tupperware tht I have made whole in the top of, and I put some of thier tank water in the bottom , just a small amount , then I take a pc of styro and use 4 skinny pcs, * I break them to size) and I glue them to make a square, then I lay a pc of cut to fit plastic canvas on top of my stryo boat" , and I also use sticks, I cut them to fit sideways on the canvas, you can use skewers, or bamboo chopsticks. or any plastic, *( idea is to have the clutch not laying flat on surface, so when they hatch they will crawl diown and evntually get into water . *( good ) ~~ I then place my clutchs on the sticks and be very careful placing the whole boat with clutches into my small tupperware, now cut many holes into top, and make sure when you close the top, your not crushing snails, if this is , reduce your water, or cut your stro in half lengthwise so everything fits perfectly .
now I can usually get clutches to hatch between 2 days !! and sometimes a week .
the trick is I put the tupperware on top of my compact florecent light fixture, where I feel the most heat , that is where I put the container. if you do not have this light You can put this system on top of your strip light , just takes a little loger to hatch, I have heard of people using thier pc towers , cable boxes etc.. just so they are getting very very warm , I change the water about every 4 days . I ck for snails then anyway

all snails in thier I pull the stryo boat out place on counter top, somewhere safe , and I just rince the new baby briggs into a breeding net .. then let the rest of the broggs hatch I just put them where they were .
O hope I have explained this good enough for you to make a nice hatery of your own, it is really easy , and can be done with items in the home

~~ HTH ~~
I will have more babies up for sale soon , right now I want to wait for more clutches, and see' what few I have left what all thier colors will be . I am also makig another snail breed out tank, so they are not overcrowded .
goos luck everyone ! ~~~~
