So I think I have atleast 1 polyclad flatworm, I have seen what I suspect to be one, I didn't get a great view but I think that's what it was. I am going to make a trap that I have seen people making online but the only issue is I can't get any clams. Nowhere seems to have any fresh or frozen so was wondering is there anything else these will eat. I know they eat snail because I suspect that is what has been eating mine. Thanks for any advice
