So I found this guy in my tank today. It looks like a baby sea star of some kind and not really sure where he came from. The only addition in the past 3 months or more has been a peppermint shrimp. Do sea stars just emerge like that or has he just been hiding for awhile?

I couldn't see anything at first in your picture but then I saw it, that's an asterina star fish. For some reason they seem to pop up out of nowhere. They can get to plague proportions if allowed to. From what I've read and heard there are two different kinds. One is more white than the other which is like a dirty white/tan. One will eat corals and the other won't. Sorry but I don't remember which one does what. Just keep an eye on it or them and if they are mostly on your glass and rocks they're eating film algae. If they're on your corals remove them and dispose

I agree with Dave 100%. I believe they come in white and tan (dirty white). I have the white ones and when it got to the point that I had 20 of them on my front glass (6'x2') I decided that was too many. So I captured them all. The next few days I had maybe 10. So I pulled all of them. It's been several months now and I rarely have more than 2 to 4 on the glass. I haven't seen that they are bothering the corals (mostly sps and lps) at all.
Hope that helps soom?

I've considered that but the tank has been up for over a year and I assumed it would have been exhausted by now.

A good idea, Test water before to establish a base line.
