if u plan on going fishing this will be useful information.

i heard the rare purple fish can be sold up to $1000!
but beware, half of the purple fish u will find are decoys that people throw in the river as a joke. the fake purple fish are worth less than a dollar...
the other fish which are not purple are worth around $50-$150. so you can either play it safe with a normal fish, or risk it all with a purple one (but u might get a fake!)
