I have one which I was debating to sell or keep and decided to keep. Mine is 7" long with his tail extensions add another 5". Those things just keep growing and I love it. There not as delicate as I thought they would be. I was always afraid of them breaking but haven't broke once despite the amount of squabbles it has had with other royals in the same tank. Would get another one if I could find one with a solid white tail since mine has allot of grey in his.
Thanks for sharing that vid matubula it was cool seeing them smaller.
