Hello, I plan to transfering into the polypterus section and I plan to take care of one of these. Anybody help please and is a 7inches polypterus considered as an adult?
No 7" is still a juvenile. Those guys get big, like 2' long. So if you have problems housing such giant monsters, I advice you to give it away now while they are small. An ornate would require a minimum 4' tank, but if you can go bigger, its better.
