Thanks. I have the 5 gal set up, i thought it was smaller.
Seems you guys are right, I was searching something else and found a pic that looked an awefull lot like my flatworm. They said it is an acropora eater! I wondered what the AEFW stood for. Pseudoceros rubroanus. It was advanced aquariest article on wrasses and controlling them. It was a possibility but not sure. The pics i have seen other than that one look a little red but i guess they can differ.
