My mate sent me a video of the results of a fish show over china way..
Anyway these two photos caught my eye..

Stunning Red Arowana..

I know that the lighting setup will have a red spectrum to enhance the Arowanas colouring and scales..

Second is this aquascape..

I think they are bent roots with attached plants..
Im also sure that the roots are man made..

Stunning though..
