Well first of all this fish is very easy to take care of and will eat flake food and possobly, mabye brine shrimp. What i usually do to catch fish from streams is make my own net/trap. Depending on the size of the fish the net will vary. I used some old window screens to make a trap with bait inside to catch some small fish. Or you could just buy a net and try to catch them that way. Hopefully what i just said will help. Anyways good luck!
