Oi 8 is a lot. And those are ones you found... Do you have blue/black leds? That was the only way I could see the babies that small. Btw, the babies in my tank seemed to be attracted to my UV-B plant light. They crawled up out on to the glass right undwr the light. I don't know if that would help or work. I don't think my problem is over either. I was just squinting in my tank and noticed a tiny little guy. It hasn't been long enough for mystery snail babies yet, unless it hitched a ride in the shell of a bigger one that just came in. I really regret the first pest that made it in.
