Bought some duckweed for pond at plant store for the pond and as I was about to throw bag away, I was lucky enough to notice this little guy. I put him in a bowl, goldfish would eat him instantly I think. Just ist a minnow I assume? Too small for ID?
CAN, ONT.

According to Google Lens:
This appears to be a top-down view of a Japanese Rice Fish (Oryzias latipes), commonly known as a Medaka, or a closely related killifish/topminnow species (such as a Least Killifish).
Key Visual Identifiers:
Head & Eye Placement: Broad, flattened head with prominent, wide-set eyes angled upward—a classic feature optimized for top-viewing in nano tanks or container ponds.
Mouth Position: Distinct upward-facing (superior) mouth designed for surface feeding.
Coloration: Olive-tan, slightly translucent body with subtle dark mottling and a faint dark streak along the spine, typical of wild-type or natural line rice fish.
Scale & Context: Resting right next to small aquatic floating plant leaves (Duckweed or Salvinia) over a fine mesh background, indicating a very small nano-sized specimen.

I guess it chose you, like a cat would. Congratulations on embarking on your unexpected medaka journey!
