I thought that colouration was basically linked to seasonal migrations (ie. lose gold when they get trapped up the fresh for ages - get it back when they get back out in the salt)
But that's only based on what I've heard about NT fish. ie. dry season billabongs, wet season back down to salt, lifecycles.
Or is that depending on what strain of fish they are? (Is it 14 distinct variations/populations from memory?)
