According to what I've read... the eggs hatch in about 3 days. The male then moves them to a "nest". They have a sticky spot on their heads that causes them to stick on the bottom of the nest and wiggle their tails... looks like the bottom of the nest is a wiggling mass of worms. Both parents become very aggressive toward anything that comes near the nest.
After another 3 days the nutrition from the egg sack is used and the fry leave the nest to feed on plankton. The tiny fry are herded around by both parents till they reach several inches in length. A baby peacock bass can reach a length of 12 inches in a year.
