Success!!!!! I made another type of feeding stick from 3/16 plastic tube and monofilament line. Threaded the line thru the tube and taped one end down. Left 3 inches of excess line on the other side and skewered the silverslide on that. Set it in the tank and let the flow move it around until it got his attention. Moved it away and then closer to him and bam he ate it. Must have been stick shy from when he missed the food and bit the straw. No hesitation this time just like the first feeding.
