Wife calls me at work an says, "wtf is big and spikey in the tank?!". Puzzled I respond, "coral!?!?" lol. She sends me a picture. I wish I could post from my iPhone. A big ass black urchin magically appeared in my tank. Guessing he was a hitch hiker from a coral order. Haven't seen him before but man what a great free gift. I'll see if torx will post it.
