Nassarius aren’t super predators. I have several species that can’t right themselves in there with mine and generally I catch the ones that have fallen before they’re able to eat them. Spiny nerite snails, cerith snails, and margharita snails all coexist fine with my nassarius.Unfortunately it is, and they are carnivores. I have the same issue with my 3rd and 4th gen Trochus snails. Each snail serves a purpose, and I will never say this one is bad for that reason. They are only doing what they were meant to do, clean up the tank. I will likely give away my Nassarius to another reefer as they are good at cleaning up left over food and such, but, I want to keep some other snails that I can't allow to be consumed because they fell over.
I agree, they are not out to only go after snails, but they are super opportunistic.Nassarius aren’t super predators.

The ones in the picture aren’t. Whelks have a tattoed trunk and a trap door that closes when they retreat into their shell that you can see on the end of their bodies when they are moving. Whelks also have a sort of different shell style. Or at least mud whelks do. Hard to explain without having one in person for me to take a picture of.Those could be whelk
Why specifically spiny astrea? I've never actually kept those-- only the standard astrea.I like to stick with a mix of trochus, spiny astrea and nassarius for this reason.
Well, they seem to only prefer the rocks (along with ring cowrie) - whereas the trochus love the tank sides and the nassarius the sand bed.Why specifically spiny astrea? I've never actually kept those-- only the standard astrea.
Spiny astrea are natural tanks as well. They have a door and their shape means it’s really hard for them to fall over in such a way that they won’t be able to right themselves.Why specifically spiny astrea? I've never actually kept those-- only the standard astrea.
