Has anyone ever had mexican Turbo snail, just, disappear in a nanotank? I have a 12g nanocube, and I just bought a mexican turbo snail , which was full-grown, a couple of days ago. About a day ago, I noticed that it was nowhere to be found. I even did a water change today and there was no sine of it back in the filter housing. Any ideas of where it went? They dont dig do they?
