Quick question, I recently bought my first saltwater tank, nothing too crazy just a little 5g fluval Evo and I threw in 2 peppermint shrimp, I have live sand and about 7 lbs of DR and .5 lb of live rock, I noticed today that I have a worm in the tank, since I’m new to this I have no idea if it’s a bad worm or not, it’s black/dark brown in color and hair long tentacle like hairs, I’ve also noticed a spider web like strand on my LR, I’ve looked everywhere on google and it might seem like a spaghetti worm, can someone please confirm this!
