On the glass this morning. Can anyone ID what these are? I recently add five new coral frags and a blue tuxedo urchin. The corals were removed from their bases and dipped in Coral Rx and Bayer respectively. Maybe something that hitchhiked in on the urchin? They've hung around all day. They're 1 to 2 mm long. I'm thinking they're some kind of copepod larvae. I seem to be getting a bloom of copepods crawling around at night. I think I'll be ready for that mandarin soon.
