Does anyone have an idea what this is? It pulses several times every few seconds. I’ve got a gha outbreak currently. Tank is 10 months old.

Yeah I’m at a complete loss of what it is. To make matters worse it’s moved now. I’m just wondering if it’s harmful

they are exactly that. Upside down jellies, I have a ton of them in their polyp stage attached to my rock. I thought they were baby aiptasia. So I was kalk pasting them. Which btw does kill them and I can confirm copperband butterflies eat them in their polyp stage.
