Born to be bad: Agonistic behaviour in hatchling saltwater crocodiles (Crocodylus porosus)
While the full repertoire of behaviour was displayed by hatchlings at 1 week of age, a smaller subset based on dominance status was displayed among 13- and 40-week-old hatchlings, and agonistic behaviour and social status may be major contributors to the observed differences in growth rates and survival in captivity.
Agonistic Behavior of Captive Saltwater Crocodile, Crocodylus Porosus in Kota Tinggi, Johor
The study shows that C. porosus was more aggressive during daylight, feeding time and non-feeding time in breeding enclosure as compared to non-breeding pond where it is only aggressive during the nighttime.
Aggression and Competition for Space and Food  in Captive Juvenile Tuatara (Sphenodon Punctatus)
As juvenile tuatara mortality is female-biased, and aggression against females in bigger male-biased groups common, I recommend keeping sexes separate, and assorting groups by size with more spacious enclosures for male groups, which should improve health and numbers of juveniles for release, improve recruitment into the reproductive adult population, and ultimately create more successful head-starting facilities.

The Runs test showed that the behavior of C. porosus had a pattern in daily activities, based on Mann-Whitney U test.

Crocodylus johnstoni in a Controlled-Environment Chamber: a Raising Trial
Crocodylus johnstoni hatchlings were raised in a constant-environment chamber of the type used for Alligator mississippiensis by Joanen and McNease, but may not be as suited to this style of raising as are some other crocodilians.
Growth rate and plasma corticosterone levels in juvenile alligators maintained at different stocking densities
Crowding of juvenile alligators inhibits maximum growth and that the subsequent stress associated with this crowding results in chronically elevated plasma corticosterone, which shows a strong negative correlation with change in body weight.
