very nice fish pauline
size tank/numbers ?
Minimum ideal tank size - 4 feet. Say a standard 55.
Numbers - if kept as part of mixed gender tank 1 male to 2 or 3 females. A 55 could accomodate say 12 Peacocks comfortably in 4 groups of different species kept like this.
If kept as an all male group in a 55, then just 1 of these, and again say 12 in total, all male, seeking to avoid similar colourations so as to minimise/avoid conspecific aggression.
