Observation about minnow feeding

[FunkyRes]

T elegans [elegans,terestris] are generally not fish eaters.

T elegans vagrans (and the now invalidated klamath subspecies) are quite adept at catching fish and frequently feed on them in the wild, even from rapid water. Just noting that to be clear. See Stebbins for more info.

Note though that in this observation, the measuring cup has more and deeper water, the garters have no trouble catching the fish - it is the fish in the water dish they did not consume.
