Warnberg,
You said you pulled a few from the tank? Did they break off part of their body when threatened? Sounds like Stometella(I think). They also can be seen squirting a fluid like substance from their nostrils/ mouth, which is said to be beneficial the reef. I could be wrong, but I originally confused Stometella for baby turbos. BTW, if that is what you have, they will continue to reproduce, I have tons of them.....No problems for me, I put as many as I could catch in my fuge to help them reproduce safely...
