A tandem hook set up can be used for freshwater, not so freshwater and saltwater. A wiggly, worm/nereids pattern is possible with two stinger type hooks. I was researching various nymph rigging setups and came upon a saltwater multi-fly set up, which led to the tandem hook set up I thought worth sharing. It provides a worthy fly pattern for various species of fish. A smaller version of Derek Fergus’ MOAL pattern.
