Just set up an IM 25 Lagoon a few weeks ago and transferred everything from my previous 10 gallon pico. All corals and the lone fish in the tank are doing well. However, I started seeing hundreds of these guys showing up on my glass in the last 36 hours. They are tiny, about the same size as the tiny white copepods you see on your glass. I actually thought that's what they were till I noticed some that did not move.
Greatly magnified picture. Are these hydroids? Just let them run their course?
