Aquariums: Ramshorn snail – All dressed up and nowhere to go

Noticed this dude crawling along my guppy grow out tank with a little bit of decoration. This tank sits by a window and has some carpet algae issues that I'm still working on. It's a 15 long and I have the short end facing me, so it's hard to see all the way to the back with the way I have it scaped. Apparently it has gotten to the snails. I'll have to clean him off and put him back, but thought the train was pretty.
