The development rate of fertilized eggs varies depending on
ambient temperature and dissolved oxygen content of water
(Mariscal, 1970). In the present study, hatching occurred
152 h and 10 min after fertilization. The cleavage pattern of
A. akallopisos is as same as of the other anemonefish
(Rattanayuvakorn et al., 2005; Dhaneesh et al., 2009). In
A. akallopisos, the yolk had different sized fat globules
dispersed in the vegetal pole, as reported in A. polymnus (Ross,
1978). There are variations in time and stages of embryonic
development among different genus and species of fishes.
