Glad to see these guys are still out there living it up! I believe that my numbers have dwindled down into the 30s. Haven't taken a census in a while. Living in a fluval 13.5, these guys kept going through the overflow and getting stuck in the filter material and perishing. They are finally big enough they don't fit through the slits. Now the only threat is our big hermit that gets the need for fresh snail from time to time.
Sorry to not give any updates for the last 8 months or so... Fire season picked up in July; I was pretty much gone from the end of July through the middle of September. Then the hobby got put on the back burner. Tank is still going strong. I might be able to part with some more of these, let me count tomorrow.
