now I have an infected 16g tank that's covered in those bad snails that reproduce a-sexually and I've been cleaning them out as I can. I also have a pair of mystery snails that I bought at petsmart (both blue mystery snails in that tank. no light ivory or golds). but here's the oddity. I know what the bad snail looks like. they are elliptical shells and a clear body. the mystery snails are bigger with dark shells and a black body with some neon coloring. BUT! here I am looking in my tank at a small snail that has the shell like a sulawesi and the body of the mystery snails. nooo clue how it got there. it's still small, so curious if maybe it's a mystery snail baby?
