Is this worth keeping?

Hi just became financial member been looking for ages. Returned to QLD after long time away and cannot remember what some fish are that I catch. Caught a few jewie looking fish up the Caboolture River today and they had purple colour rounded noses on them about 30 cm long. Could someone tell me what they were?

Looks like it but these had a light purple bar about an inch wide running from the mid section to the anal fin. Will I be the new David Attenborough of the Caboolture river? Hope so, need the money.
