So I've had a new saltwater tank sitting for a couple of weeks since like a little bit before New Years of 2023. I used to have 2 clownfish but there was a parasite that killed them both that they apparently had both had from the place I'd bought them from. So, as suggested, I've set my tank to 80 degrees and I'm letting it sit for 60 days total before putting anything new in. All there is in the tank so far is a Xenia coral fragment and 2 live rocks. I was looking over at my tank and saw this little guy in there. First of all I'm wondering how it even got here in the first place and second of all what it is and if it's harmful to the tank.
Thanks,
