A friend was looking at my tank today and noticed a tiny fish swimming around in the spines of my sea urchin. It turned out to be a baby Cardinal. I am assuming that there were probably more babies than one....but I don't see any more. I think this one got lucky that he took shelter in the sea urchin. I took him out and put him down in my refugium? What's the best way to care for a baby Cardinal? Will he eat cyclop-eeze. Hope he makes it.
