I live in a small town in alaska, as a fish enthusiast i am very limited as far as resources go. That being said, i have a 55 gallon tank that my daughter left about two years ago with a female convict, a 12 inch albino pleco and two red eyed tetras . Last week i added 2 two inch Peacock cichlids (apparently). The convict took to the new peacocks like they were puppies. Even the tetras school with them. Make no mistake, my convict will kill anyone she will not accept. My concern is that i dont know what species they really are and when i will be able to sex them. I think they are both males because of the vivid yellow coloration. I would like to have more but too many males would be bad. Does anyone have a suggestion? They have brought life and youth to my old fish, its great!
