greenterra;4080093; said:The pattern distinctness will depend on the individual but generally they have more defined patterns as they get older. It also becomes more stable with size and age.
For sexing, males will have a much darker defined pattern throughout the unpaired fins and lower gill plates.
Females will usually show a lighter, more even drab appearance in the unpaired fins with often little pattern to the lower gill plates and often have much more baring down the flanks.
