Small trout minnow
A short, slim minnow inside the size range the model gives stream trout. Small profile, light body.
What is a trout minnow?
A small minnow bait presents a narrow prey-sized profile. This six-cell balsa version has a single-cell lip and no ballast; the Tank tests whether it can track, while fish scenarios test its modelled length against each species’ prey window.
What the model actually measures
The grid uses 1 cm cells. The Tank computes displaced water, centre of mass, lip force, tracking stability and wobble at its default retrieve speed. It does not predict a running depth or a catch rate. See the equations and limits.
Balsa, six cells long, a single-cell lip below the line tie, no ballast.
Tank verdict: Swims
Swims, but barely moves. It is so heavily righted that the lip cannot push it off-axis — a stiff, tight, lifeless action.

- Take out some low ballast or add lip area to loosen it up.
- Line tie is almost on top of the lip. Very little leverage, so the action will be muted.
Compare with the jerkbait
Both designs run through the same Tank model at its default retrieve speed. These figures describe the block builds shown here, not commercial lures.
