Babies!
 

Ok so i just discovered two very small ring cowries in my tank, started with three a year ago and now five. Over the years of reefing i have never seen this, so has this happened to others? I know there not from the rock as all lr was realreef and it was all inspected.

Ring cowries readily reproduce in the aquarium as the female will guard her egg clutch and I don't think the babies go thru a planktonic stage. My ring cowries have reproduced as my original five are over 10 now and I have found shells of various sizes. I'm hoping to see if the Money and Chesnut cowries I have in other systems reproduce as well
