I have a randam snail that has grown from being tiny. I have 2 nerites that have layed eggs all over
But I thought they couldn't survive in fresh water
I also recently got a new java fern which it may have come from here are a few pics
It's a pondsnail. A pest often, but I have them in almost all my tanks. The y often stop at the carrying capacity of the tank and did off, but then come back. It's really not an issue for me...
