Hello, Im from spain, here is very difficult find this fish. Today I find one of this about 2". Congratulations on your Festae find.This specie what is? Amphilophus or Cichlasoma? As far as the genus classification, Jeff Rapps (cichlid breeder/importer/vendor extrordinaire) used to list them as Amphilophus but has recently changed his listing to Cichlasoma so I guess they're Cichlasoma Festae when start female show red colors? Females start to show their vibrant red color at about 4"+. It grow fast or slow? Females grow very slowly and males a little faster. thanks
