nice collection of pics. i saw one in the lfs a year ago or so that was 27" wish i could of got that one as it was only $60. mine is now at 14"+-. i'll try to get some pics of it up. i noticed it gets nippy with my ornate now and then, the ornate normally starts it.
$60 seems very cheap for 27" Congicus. Normally @ that size, it would cost several hundred.
Amazing collection but such a pity, he lost the upper jaw bichirs in his other tank.
