Nibble fish

The nibble fish is a fish you catch in rivers. Look for a tiny shadow. In the northern hemisphere look for it in May – Sep, from 9 AM – 4 PM. It can only appear after you have caught 20 fish. Nook's Cranny pays 1,500 Bells, C.J. pays 2,250 Bells.

An X-Small river shadow that only bites in the middle of the day, after 20 catches. At 1,500 Bells it is worth casting at every tiny shadow around lunchtime.
