Hi all! I last cleaned my 5 gal (fluval long rectangle one) shrimp tank about a week ago and at that point my snail hadn't been moving for a day, so I picked him up and sniffed. He seemed pulled into his shell and didn't smell, so I put him back. Today I realized that his trapdoor was laying in the middle of the tank and his shell still looked dark, so I was going to pull him out... the body's gone! The shell was just full of sand. I'm -pretty- sure that when I took him out last week, he was actually still in there, though I could be wrong. And I can't find his body in the tank. What I have in that tank is about 40 RCS, about 10 adult adults, 20 mid-sized but breeding age adults, and 10 very small ones. And probably some more shrimplets. And then a few MTS. Is it possible that they ATE him? I don't have a problem with this, but I'm wondering if I should start sifting through that tank trying to find him. The only thing different is that the nitrates might be a little high, around 20 ppm? They're normally lower (inverts as only bioload, lots and lots of guppy grass and a few pieces of duckweed as well). Ammonia is 0 or 0.25 ppm. 0 nitrites.
