creature

Hii, I just found some really strange strings behind some rock work. It literally has the structure of spaghetti. My guess is that it is some kind of a sponge. Any guesses? Thanks!

Hi all. Only been into reefing for a couple of months. Watching the tank from a distance and seen my zoas starting to close. Saw this creature moving extremely slowly under them. Moved like a snail with really long hair like tentacle poking around. Photo to follow. Was searching as fast as...

Hi, Put a new piece of rock in the tank recently and this thing has suddenly appeared at some point today. Anyone any ideas?? It looks as though it’s “breathing” in the video but I can’t be sure with it being on the power head. Every days a journey with a new reef tank

So I know the picture is blurry but I can’t get a great shot. Found this little Slug looking thing in my tank today out of nowhere and wondered why if anyone can identify it and tell me if it could harm my aquarium?
