Ble snail eggs
I have same thing but my Blue snail has dropped 4 of these things already in 2 days i have no idea what to do i have heard all sorts of things like they won't survive, but I am in Awe. My water line only leaves enough room for the snail and these sacks. When I didn't know what it was, as I am new to all this I removed one and the next day I had a little silver fish like looking thing running around in the bowl. I just don't know what to do, It keeps laying these things. The only reason i found them I was cleaning the tank and lifted the lid, they were all up there. I am trying to find answers, anybody know any helpful facts? lol please!
