A mysterious infestation of snails...
I have a bit of a puzzle on my hands: I have a tank to which nothing has been added in months; the last thing I added plant- or fish-wise was some water sprite back in August.
However, as I was performing a large water change today, I noticed what appeared to be baby snails on the glass! I crushed all of the ones in sight right away, but I'm still perplexed; were they dormant on the plants or in the gravel (Eco-Complete) and simply waiting for prime conditions to hatch?
This is the first time I've had snails in the tank in about... the sixish, sevenish, months I've had this tank running. Comparing them to mental images of young snails from an aquarium many, many years ago (long gone before I started up the hobby again), they look to be pond snails; I can find no adults in the tank to compare them to, only the mysteriously appearing babies.
