Tectus breed in that way.FWIW when my turbos reproduced it was them puffing white clouds into the tank (sperm) and then laying eggs never saw webbing like that during the whole process. I think there is something else going on because this does not seem like turbo snail spawning to me.
What is this stuff? Kinda looks like spider webs. Thanks!

I'm not really sure if the Turbo snail in the link below is what were all thinking of, but here's a cool little video regarding reproduction.
