So yesterday i finally brought the little guy home. from what i know, he was tank born, lives in warm water, and has not much webbing.i'll get an aprox size when he comes out, but he isnt very big. he is eating hermit crabs.
Most aquarium stores will have a feeding stick (they are a plastic stick with a bent tip and a loop at the top, usually clear with yellow ends) but you can use bamboo skewers (found in your local grocery store) or even a piece of air line tubing or pipette. My Mercs seem totally unaffraid of anything made of clear plastic - no clue as to why.
