I might be interested in the argentea in a couple weeks, I'm grabbing two from Sam and will be down that way shocking fish on the Willamette soon. Gives me more selection to pick out a keeper.
Considering the smaller male is smaller and the less dominant male, I'm fairly certain has more potential for nuchal hump than the larger male. His is more noticeable than the larger male's.
About how big are these guys right now? I have an open 125 with a 5-6 inch creamsicle and I'm thinking about acquiring a 5-6 inch barred. However I'm thinking that they might already be too large to even take the chance in getting them to get along.
