Hi, I put in two sea urchins about a mid December. I realized two weeks later there was 2 bangaii cardinal fry swimming around the urchin. I then noticed there were more in the fathers mouth. I kept an eye on them throughout the day and not much changed. When I checked on them in the morning the two fry were at the top of the tank next to the overflow box out of the protection of the urchins. I decided to put them in my refugium away from the other fish. I didnt see any other fry in the tank or even in the mouths of the parents. A couple of days later, I noticed two more in my overflow box. It wasn't easy but they all made it safe to the refug. It is now a little more then a month and they are still going great, eating well and getting much bigger. These are some pictures of the father with the fry in his mouth and the baby fry in my refugium, I hope you enjoy them.
