Ok I will bite.......
There located in a protected area under heavy conservation and basicly is a wild life refuge through this whole river sysytem. You can catch them all day in this area called the Sao' Benidito River system. I have memorized this location by heart and it is located a whole lot more south then on the map indicated above. Though there may also be some Fogo in the area listed on the map above but I am not familiar with those location's as being the location of the "Fire Cichla:". Ok I have shared enough good luck with your search we all have been looking and waiting for more information about this coveted cichla. (SOME OF US LONGER THEN OTHERS). There is a fishing lodge that is located on the banks of this river system that offers catch and eat but no export. I have been told just to get there is a challange all by itself.
Hint: Look into some of the old timers thread's. Let's just call them the PRIMES they have a lot of information they have learned over the years and from time 2 time they do share information. GL.
