For smaller fish like that, I would suggest the bottle fish trap. It's really easy to make and I have had a lot of success with it.
At the widest part of the bottle, cut the top off. You should now have a cup and a funnel. Stick the funnel in the cup upside down. Bait the trap and try to put it somewhere you know the fish frequents. Then, just wait. The fish swim in, but usually can’t figure out how to get out.
Here's a couple pics...
