My 2 foot Eunicid Worm

[Samw]

I can't say for sure that this worm preyed on small fish at night. However all of my small gobies dissappeared over time. Also, something took a bite out of my baby Hippo tang earlier this year. 20% of its body was completely bitten off overnight and I don't think it was from one of my other fishes. I didn't think the tang would survive but given how healthy it was from the start, it survived and has healed 100%. I wish I had taken pictures to show the before and after of the fish to see how amazing the bite and the recovery was. I don't know what else in the tank could have taken that bite. I have seen this worm carry rocks around its cave like they were nothing so it is not hard to imagine this guy grabbing a sleeping fish. I have also lost all of my ricordia and zoas. I feel more confident about buying new corals and gobies now. If I buy a new Ricordia and zoas and they stop getting eaten, and if I buy new gobies and they stop dissappearing then I'm pointing my finger at the worm.
