Figured I'd add a few more pics of some recent minnow catches. First off this time is a Rudd (Scardinius erythrophthalmus). These are invasive and most similar to large golden shiners with the most obvious difference being the red fins and tail.

From the same spot, I also caught my first spottail shiner (Notropis hudsonius). Hornyhead chubs and bluntnose minnows also have a prominent spot at the base of the tail, but bluntnoses have crowded small scales behind the head, and hornyheads have orange fins/tail

Northern Pearl Dace (Margariscus nachtriebi) - the original topic of this thread and I finally caught my own. Small mouth and small scales with scattered dark scales along the sides and a complete lateral line.

Central Mudminnow (Umbra limi). Hard to confuse with other species. Has a rounded tail, large mouth and a dark bar at the base of the tail. Can live in warm, stagnant water as they are able to breathe air. Not a minnow at all, but is actually related to pike.

Rainbow Darter (Etheostoma caeruleum). Certainly one of Ontario's most colourful fish. This is a male, the females aren't as colourful. This is also taken past prime spawning colour time, they get better looking than this!!! Most similar to Iowa darters with the most obvious difference being the bands on the rainbow go all around the torso while on the Iowa, the don't extend onto the belly.

A very interesting topic for sure.. Fossil fish, thank you for taking so much time to put up so many great shots of the variety of 'minnows' we have in our province

Looks like a sculpin---must be related.
Darters are from the same family as perch and walleye.
