If you do not know the exact type, how will you know when it is mature?
Yoda has Spoken! LoL.
You are right though, I don't know when it will be mature. But I have to say, alot of our knowledge in the Hobby regarding these species comes from "Word of Mouth." Very little "Printed" information is out there regarding rays, thats why I'm here. This place is great for information like that!
If anyone can I.D., Please post!
