Male or Female aggression

Adult males are more aggressive when they encounter another male, but other than that, both males and females are about the same. Aggressive level depends more on individual differences such as molt cycle and previous experience than on sex.

I figured that but wasn't totally sure-also about how long to Peacocks live in a home aquarium?

well it all depends on if they have good molts or not.
the #1 killer of mantis shrimp is a bad molt.
other than that ive heard of mantis shrimp lasting 5 years.
you also would have to worry about shell disease too.
