Hello everyone, I hope this message finds you well. Attached is an image (as close up as I could get of a new arthropod in my system. I believe it is an unwanted sea spider. I have only noticed them on glass and back panel of my AIO system. There are a few dozen at this point and i only noticed two initially. Please correct me I'm wrong and share any control methods/guidance. I thank you for your time in advance.

Looks like a medusa hydroid. Pretty common in new tanks. Some say that they can irritate corals, but in my experience, they don't last too long, and don't cause too much trouble.

It is a new system, doesn't seem to be bothering corals, just let them be and go away on own...sounds good to me. Thanks bud.
