So my old soil, was a mix of Cocofiber and perlite and sand. I though that holds tunnels for Chams, surely it will work with snail's. I don't think they liked it. There was a bunch of holes in the dirt, recently, but no eggs. I changed the soil out for straight eco earth and they immediately laid. There may be a benefit to some sand, but way less I think than what I had.
However that soil was pretty smelly, I was told to try to not change it, as they add their bacterias to it, and it is beneficial to them. That could have played a role, but they seemed to have issues digging in it deep enough.
Temp, I just keep them house temps. Nothing special my house as we use a Swamp Cooler and Propane heat, varies quite a bit. 60-80, some nights in the winter sometimes down to 50, and they have been fine through it all.
Humidity, they like it wet. They don't seemingly need a ton of air holes. So just like you would keep an Isopods or something. If it gets too dry, they will be okay, but they will sleep. They aestivate (probably didn't spell that right) so they will attach themselves to the side of the container, and make a mucus to seal up against it. This allows them to sleep, Humidily inside of their shell. Apparently they can do this for up to 2 years at a time.
If it gets too dry and this happens, just spray them with water and the water breaks the seal and they wake right up. It happened to me twice. The second time, I just said screw it, it was mid Winter, I had other stuff going on, didn't think they would breed in the winter so just let them sleep. I let them sleep almost 2 months, my wife was positive they were all dead, sprayed them and boom they all sprang up hungry and happy. So if you need to slow breeding or whatever this is an option. I'm not sure how this affects their lifespan, as they don't grow or eat during this time. I think it's a sort of deep freeze, of their system.
They can live for a very long time I am told, in captivity up to 10 years, I am not sure how much of that is influenced by sleep though. As I have been told, no Aestivating they will live 3-4 years.
They are Hermiphodites (I know I didn't spell that right) so when they mate, both may have babies, or only 1. 50-120 eggs per clucth, usually around 80-90.
So this next part. I don't know for sure, I have seen some studies, but there could be so much more going on there that I am not going to make assumptions.
I have been told that you need to make enclosure size 1 gallon per snail. Obviously that's insane. But that is what the snail lovers suggest. Now I seen a study, they had snail's in a 5g and a 10g and a 20 gallon setup.
They had multiple groups, and they said that 30 snail's in a 10 gallon had the most effective numbers, or 60 in a 20gal, and 15 in a 5. It was not badly effected by growth, the rates were acceptable and the loss of the 10 gallon after a 6 month period (hacthed to adults) there was still 27 remaining (similar numbers for the other sizes).
There was Zero losses, for the 5 to 5 10 to 10 and 20 to 20. And their was like 18 of the 20 for the 10 gallon 20. The 40 in a 10 dropped to 24. So they had showed, 3 per gallon is ideal. They did not say at what point the die offs happened, so to contrast babies vs adults, as we will not let them grow full size we can probably have more.
Now to add another element, they used a semi low wooden box. In my experience, the snail's spend most of their time on the glass (sides) of the enclosure. Or the roof if it's soild, like a bin or glass top. They go to the soil to lay, and eat that's about it, sometimes they walk across it and any branches, most of the time not.
I have seen and been told, if you put a bunch of pieces of plexiglass stacked height wise, like roaches egg carton, that you can increase snail's per gallon. If they get overcrowded, they will release a toxin (I was wondering if this was the soils smell) that will kill off some of the colony I guess.
So if you use like a fish tank, (which works well, with an acrylic lid) you could silicon pieces of acrylic or something for more climbing area, maybe do it like a roach enclosure where it's only half, and leave a food area.
They poo alot, so your going to have to clean that, I just mist it down, so that helps with humidity too. The poo also provides calcium and a PH balance to the soil, and I am told beneficial bacteria, so do this, and if the soil stinks really bad, swap it, but keep some of the old and mix it into the new. Usually every other day, when I feed. They eat a insane amount, so make sure to feed alot until you get an idea what your colony can eat. Also throw cuttlebone in there, as they will eat it for calcium for their shell.
If you go take them to feed or whatever, when you try to get them off the surface, Slide them. If you pull it's like a suction cup and you can kill them pretty easy they have a firm grip on glass/plastic ect, so slide them a bit, and it will loosen and remove easily.
. But our 2 in the CK just laid about 90 eggs.
