spearers will not make the clicking sound, and you can feed them druning they day depending if they are active during the day. If its burrow is closed up, then dont feed it, but if its open, it will probably come out it eat. For food, I gave mine some frozen raw white shrimp I got at kroger, but I had to chop them into smaller pieces. One bag of shrimp lasted me over 6 months of feeding (along with giving it snails and hermits too).
