I've been chasing some gold and turning it brown.
Things are firing up. The large brown and the bright brown lacked elastomers and had intact adipose fins so likely wild to the river where they were caught. The rest were eager stockies.
Beautiful fish! But what the heck is an "elastomer"? It sounds vaguely kinky.

I think they call the bright ones palmino's.
