uh, sorry so long to post but i had a titan for a brief period. he was 6 inches of pure bastage. beat the crap outta everything in the tank, including fish as well. mine got fried with an electrical short during the monsoon season out here. These little beasties get about 13 to 14 inches in captivity. kinda stunted, considering they get over 18-24 inches. maybe someone else has a bigger fish story>? also, try fishbase.org. they will have the whole skinny on those masked bandits.
