I have been trying to figure out what has been happening to my red ramshorn snails in my tank. I know that loaches eat them, so I moved the loaches to another tank. Then this morning I found another group of snail shells with no one home, then I found this monster sucking the snails out of their shells!!!
The large female was have a buffet of snails. I have never heard of any Syno eating snails or caught them in the act.
