Cohabitation
Keep singly. Forest cobras also eat other snakes and are large and defensive – one animal per enclosure is the only safe and stress-free solution, not least because during every task you must know where the animal is. For breeding, put them together only briefly and under supervision.

Notes

It reacts defensively to disturbance and does not flee at once; a very good swimmer, semi-aquatic and climbing → a large, well-secured terrarium with water and climbing opportunities. For experts only.
