You can collect, who says they are restricting. If you can get passed Mexico's check at airport you are kinda home free. Mexico has laws that dont make sence when it comes to fish/wildlife...well many US laws dont makse sence either, but back to Mexico. Cichlids are eaten every day by locals, and the gov. and buisneses kill cichlids everday, due to the massive polution that goes into the rivers and lakes. There is no restriction on collecting. As long as your not trying to bring back 100's your good, but even that has it's ways.
