Male Colombians get about 5-6 feet and females get about 6-7 feet. Males can be handled alone without a problem MOST of the time, there's always the exceptions though. My biggest female is about 8 feet, but most of my females are around 6.5 feet. My biggest male is barely 5 feet, but most of my males are around 4-4.5 feet.

Hope this helps...
