We are the Colorado breeders from whom Brian and others have picked up some Nassarius babies (see other threads). We recently moved our extremely large specimens (3" - 4" yeah we know they're not supposed to be that large) from the refugium into the main tank. We had moved them down after we found them attacking some newly added clams. They only seem to bother them if the clams are unhealthy or stressed.
A couple of nights ago we found mama snail on the glass very still and determined that she was releasing a series of large egg sacks (1/2" disks) in a pattern on the front glass. We have attached photos showing mama with the eggs both on the glass and still inside her (pretty fuzzy, sorry)
187
and another of the egg sacs in place on the glass afterwards...
188
We also have one blue light shot of the mama so you can get an idea of her size. 189
Oddly enough none of our voracious tank inhabitants have disturbed the sacs. We run a deep sand bed both in the tank and in the refugium. We feed a broad variety of foods including mysis, krill, phytoplankton, cyclopeeze, oysters, shrimp, scallops, etc. We have a 140 Gallon tank and a 60 gallon fuge.
We have had some visitors tell us there is no way these are Nassarius so we are hoping for some clarification on the species identification along with any ideas on what we can expect with the eggs (incubation period, should we remove them to the refugium, etc.)
Keep up the good work DIBS and friends!
