Does anyone know what this is?

I don’t know if this is just food stuck to the power head but it looks kind of scary lol

Did you put live rock in your tank? 'Cause I swear it almost looks like a baby octopus. It probably isn't, but sheesh.

Why don't you turn off the powerhead and touch it to see if it moves?

I actually have not added any live rock to the tank. That would be pretty cool though!
