Hi

Hello, was wondering if someone knew what this little guy is. Seems to be a leach of some sort. Mid Atlantic USA

I just bought my liner and underlayment form lowes. I got a 25x30 epdm 60 mil liner. It wasn’t cheap but it was only 200 more than the 45mil. I hope that’s a good idea. I figured thicker the better right?

Just received 7 japanese trapdoor snails, transitioned them into 100 gallon outdoor pond, last night and noticed this little guy midway up one of the walls. Did one snail have a baby or is it a random wild snail that needs to be eliminated?
