In some species these eggs develop into small juveniles before they are released from their parent.
Very small juveniles have also been observed in tidal pools in Ceará.
The young follow their parents closely for a few months, and often two adults are seen swimming with two or more small juveniles.
Most of these individuals are seedlings or small juveniles.
As small juveniles, they feed on insects, small fish, and small crustaceans.
A group of small juveniles can prevent jumping spiders and oecobiids from entering or leaving its nest.
Males do not feed during the one-month period while larvae and small juveniles are protected in this fashion.
Newborns and small juveniles have large, solid dark spots and few denticles.
It is possible, however, that these rates may not reflect mortality over the range of habitats occupied by small juveniles.
Finally, the small juveniles may be collected for the aquarium trade.
