I was wondering if it is possible that the unidentified snail, possibly olive snail ate the margarita snail. I guess not.
I took him out and put him in a container. I am taking him back to the LFS tomorrow. I wanted the nassarius snail, but he didn't have those and said these would do the same job. Yes I guess he did, but I could do without the carnivorous behavior. I saw him take out one of other margaritas, shell and all.
Thanks,
Angie
