I actually have a dipnet that is almost exactly the same as Jonah's aquarium dipnets. The problem is I can't actually see the fish, I've just found some washed up dead before. So I know they are in there. If you look up Lassiter falls Crabtree creek on google images you will know what I'm dealing with. It's an old dam on a creek. Under the dam there is fast clear colder water that gets pretty deep at some points. As you go downstream its a slow muddy river.E-mail Jonahs aquarium who specialized in Dipnets for collecting natives (they have over 20yrs experience in catching and breeding natives).
