Product Overview
Fathead minnow fortresses are specifically designed as a fathead minnow spawning structure, allowing a single male to claim each tube as "his" area for the season. Male fathead minnows are very territorial, and the design of the ABI fathead minnow fortress maximizes nesting sites by limiting visual contact between neighboring males - meaning they will spend less energy on fighting and more energy on attracting females and caring for the eggs.
This downloadable manual includes step-by-step directions to build your own Fathead Minnow Fortress.
