I was checking out my tank and I started counting my emerald crabs and I noticed that I now have 5 of them. I only put four in the tank about four months ago and one of the new ones is about the size of a dime which is what got my attention as none of the four I put in were that small. I bought my 180 gallon tank about 5 months ago and the person I bought it didn't have any emerald crabs and I have not added any new LR so I'm pretty sure the new one isn't a hitch hiker. I didn't think any eggs would survive. Any thoughts? I know it isn't a discarded shell as they are all moving and eating.
