I have no idea what this thing is, i just noticed it on my frag, i dipped the frag before hand as i do with all drags but???? It’s creepy and I’m not sure if i should be worried. I tried to get a good picture of it but the lighting is kind of temperamental sorry.
So I was observing my tank and to my surprise I ran into something very strange that caught my eye. It seems to be a type of snail but without a shell. This “snail” is a little smaller than a dime. Help would be appreciated! It’s kinda creepy! *See images below*
