HRPs are, in fact, quite a different fish than Convicts. Despite being able to hybridize with them, they have many differences. Convict cichlids are brown/grey with black bars. They have a more sharply pointed mouth. They have more dorsal spines. They are much more aggressive. They get bigger. They occur in different habitats. They have much bigger spawns. I have kept these fish before. I know the differences. If you have a male and female HRP, I would get rid of the convict and breed the HRPs. They are a little harder to breed than convicts, but that's still next to nothing.
