lol , that is the problem with books , there great and give the information that is right at that time , unfortunatly as things progress and new things are learned you cant go back and alter the book , this is more so with snakeheads ,the species has been pretty neglected by science compaired to most species, (hence so many undescribed species) , in the last few years things have moved on miles and people know a lot more now than they did then , however there is still many new things to learn and many 1st,s still to come in the channa hobby and its a great time to get involved
