Setup blueprint

Business setup

A rack of breeding and grow-out tanks.

The breeding guide gives no tank size for the nine-spined stickleback yet, so a business layout can't be drawn.

Male or female

Breeding males turn black with white pelvic-spine membranes; females are always less intensely coloured.
