Hoping someone can tell me what these little guys are covering my glass and if I should be concerned? Thanks

Hydroid jellyfish. Common hitchhikers and can blossom in newer setups. Tend to come and go with time. Can scrape with magnet or let them go away on their own. Nothing too concerning unless you have tiny tiny fish. They should disappear on their own.

Hydroid.

I don’t recall if they are good or bad. I think they can be more of just an annoyance.

Thanks for the quick reply guys! Much appreciated. I’m currently in the process of moving my corals and fish from this tank (which is a small fluval 13.5 to a redsea 65. I’ve been dipping the corals and have made sure no water from the small tank gets to the big tank. I am concerned though when I move the fish and CUC can these guys tag along?

There's always the possibility, but in a mature system they shouldn't be around forever.

I got this tank a week ago, a year old, picked everything up for $1k. It was in rough shape and wasn’t very well taken care of. Took me 3 days to get it clean and running right. Upgraded the return pump and actually today picked up a 4 head reef dose I’m going to tackle tomorrow. Planning on posting pics tomorrow when I have daylight
