I am normally not home when my lights come on, but I was today and happened to be looking in when they came on. I was looking at my zoa colony and found what appears to be a nudi. At first I thought it was a messed up zoa as it is the same bright glowing green color. I was not able to get my camera in time as it scurried under a rock, but found a similar looking thing online. I am pretty sure it is a nudibranch, but could it be something else or is there something similar that is not a nudi. It is only about a quarter inch long atm.
