I know this may sound dumb but I figured i'd ask. Today I was watching my eels in my tank and I noticed that I have some new tankmates. Which I kind of stumped on how it happend. What I can tell is I have some Anemones, and some other types of coral life. Heres the real question is how did this happen I have had the rock for three months. I don't have a real bright light source. The tank does sit right next to out sliding glass window and the sun rises on that side of the tank and I have a power jet right behind the rock. The other thing is I even noticing some other life forms as well. So I guess my question how could this happen if my tank really isnt set up to have coral life. I try to post some pictures so that maybe I could find out what I have now.
