Do I feed enough?
 

Yesterday one of my Nassarius snails munched away on my Lettuce Nudibranch. :eek:

By the time I was able to scare the snail away, the Nudibranch had a big piece (half its size) missing. I don't know whether it is going to make it.

I noticed before that the Nassarius snails always come out when i feet Mysis or other meats, but to attack a live and healthy Nudibranch?? is that common or is that a sign that I don't feed enough.

Weird... a snail ate/attacked a Nudi?? You'd think a Nudi could scurry off before being eaten, or something... interesting. Sorry I am of no help

Could it be that your Nassarius are a type of predator and not a scavenger?

I've heard that there are Nassarius that do hunt.
