This snail has been in my tank for quite some time. He was so small at first I thought he was a shell from my kids little shell collection. Is it a trumpet? Whatever it is, will it reproduce on its own, uproot or eat my plants, or kill my other snails or amano shrimp? I tried to get a good picture but it can be weeks before I see it again and it was on a leaf that was wavin around in the filter’s flow. Thanks. UPDATE: I am now seeing 8. Is this a problem I should be concerned with?
