How to distinguish red roses from fire roses?

Fire rose and red rose have good temper, less kicking, low toxicity and almost no biting. Fire roses are more "red" or "brown" in color than red roses. If we must distinguish them, we can look at them from their molting (adults only)-fire roses are dark red after molting, while red roses are only reddish, and there are some purplish patterns on their carapace, so it is impossible to distinguish larvae. These two varieties can be crossed to the next generation with reproductive ability. It can be said that fire rose is a mutated and evolved race of red rose, and there is no breeding.
