I found this in my tank this morning. Looks kinda cool but I don't know what it is. Looks like some kind of Slug. Is it safe? Reef safe? It's about an inch long.
It looks to be a juvenile type of nudibranch. These guys usually die of starvation in reef tanks due to very specific dietary requirements in the wild. It may have come in on some newer live rock or a frag attached to some LR. It is very beautiful. Here is just a sample of species out there. These invertebrates are a varied lot!
