After three days they are sufficiently developed to be free swimming and leave the nest.

The larvae are free swimming and form part of the zooplankton for a period.

They remain free swimming for a number of weeks before settling and starting to build a hard matrix.

Once they do become free swimming you can begin to feed them.

The eggs will hatch in little over a day(at 24 C), and be free swimming three days later.

Don't get me wrong, I thank those who did not complain about losing free swimming for their forbearance.

The tank must still be kept covered until the fry are free swimming.

The larvae are free swimming and form part of the zooplankton for from 11 to 30 days.

These hatch in two days and the fry are free swimming of the 5th day.

Summer brought free swimming for resident children in the health club pool.
