Hes an IDIOT!! I got 15 of them, in 3 months they over ran ALL of my tanks!! They are literally psycho snails! Very prolific, hard to kill, and can jam up certain filters if you don't have the intakes properly guarded. Great for planted tanks, but be careful, cuz he wasn't kiddin when he said they breed...cuz they DO! I ended up having to scrape them off the sides of my tanks and kill them i had so many. I would remove HANDFULS of them weekly....seriously. It all started from 15...comprende? I eventually sifted all my sand and drained all the water from my tanks so i could remove ALL of them. To put it lightly...don't get them if you don't want them cuz they are a pain to get rid of!

They ARE great for turnin the sand though!!
