Nassarius Obsoleta snails for sale Calgary

[Tarolisol]

this is what i have found from searching, but some people still think they are fine, so i guess its left up to the reef keeper.

Here is a quote from Dr. Ron Shimek

The name Illyanassa obsoleta, although related to true Nassarius, they belong to a different group.

These animals are more omnivorous and predatory than are true Nassarius and will, as you have seen, graze on algae. True Nassarius will eat only carrion and meaty based foods. True Nassarius will not prey on living animals. As you have seen, Illynassa will.

Illynassa are temperate animals that will survive for some period at reef temperatures but which really don't do well at those temperatures for extended periods. Their lifespan is shortened over what it would be at their normal temperatures.

Both of these species will depost egg capsules which will hatch to release planktonic larvae. These larvae need to be fed, and in most cases in aquaria they are, instead, food for something else. I think the odds of any of them surviving through the larval period in a home aquarium are slim to none.
