They do get bigger then 20" though not as common as one might be led to believe in common house hold aquaria.This guy would be 28" and commands a lot of respect.Mudfrog;2131750; said:Who? Been on the site a long time and the biggest I've seen was 20-21". Not saying there aren't bigger, just saying in most cases people guess on the size but when actually measuring they all seemed to be right around 20". I'd love to see some pics of a measured 22"+ beast![]()
