Picture of prolarvae stage Day 1.5.
The development of the prolarvae stage is very rapid!
The egg yolk is nearly all used up. In this picture there are two white spot on the frontal region of the larvae.  It will develop into its eye.  There is no pigment yet.  The external and internal pigment is already observe in some of the larvae but not on this one.  The pigment is black in color.

The critical part of preflexion period after prolarvae stage is day 3.  I will post the pictures of day 3 later.  The very first food providing is utmost important.  Many breeder fail after day 3. The larvae died due to starvation.

Below is a picture of day 8 larvae which already pass the day 3 period.. External pigmentation is well present and the eye of the fish can also clearly see.    It well represent the appearance of the larvae at its preflexion period.  The fish is free swimming and capture its prey at its will.  I will fill up all the gap of pictures later.  We can enlarge the picture below to clearly see this fish!
