So I've had my two Severum for about two months and I love them. My green Severum is the smallest at 2", and the Larger (I'm pretty sure it's rotkeil) is about 3.5". The green Severum is already started to become green, and the Rotkeil is currently orange. What time and how long before they develop the adult coloration? If someone could also help me with tips for sexing them that would be greatly appreciated.
