I went to feed our fish when I noticed our emerald crab. I decided to give it some food as it was at the top of the tank. As I gave it food it began to eat and angle itself more toward the light and I noticed what looked like tiny black caviar it in pouch, er whatever. After eating its punch fluttered a bit as if it were trying to circulate water to the eggs for oxygen. Will this hatch successfully if they are eggs? Will they grow up safely?
