You would have to remove the eggs and then allow them to hatch in another tank as the fry would never stand a chance in the main tank. The fry hatch under developed and do not feed immediately. They will also require very small first foods. One attempt to raise queen triggerfish which I have read about used wild collected plankton and they tried some cultured copepods. It was discovered that they were eating a type of cyclopoid copepod and possibly several others, nauplii to adult after several dph. The real tough part is that the larvae were very delicate and there is not a known protocol for breeding them yet, even though it has been done before from what I have heard.
