here is a pic of this 2 inch snail I found last week. I took a pic last night of it engulfing a nassarius snail. I have noticed a bunch of empty shell on my LS, but didn't think this was the cause. I do have two mantis in the reef, but these empty shells are completely intact. The victim was half way in the mouth of this snail and was sliming up pretty bad. I can keep buying snails, but what else will this beast eat?
