Ecology

The suckermouth minnow inhabits small to moderate size streams with clear to turbid water. They prefer a water temperature of 5-25 degrees Celsius and a mixed sandy gravel substrate. Streams with permanent flow and riffles with little siltation are ideal for this species. A highly adaptable species, it has been observed that these minnows can travel long distances.

Appearance

This species gets its name from its sucker like mouth and fleshy lower lip. They are bicolored, meaning the dorsal side is a brownish tone and the ventral side is a silvery white shade. A thin black stripe separates the colors, and a black spot is located on the base of the caudal fin. Males typically are more colorful, while females are larger to aid in reproduction. They range from 5-13 cm.

Life Cycle

Phenacobius miribilis spawn in groups in between late spring and early summer. Spawning temperatures are around 14-25 degrees Celsius, while temperatures required for the embryos to hatch is around 17 to 23 degrees Celsius. These eggs are laid in gravel beds and require no parental care. This species has a lifespan of 3-5 years.

gollark: Immutability is a saner default, and `const` does not, as far as I know, work on, say, any data structure.
gollark: I also don't like that basically everything is mutable by default.
gollark: As much as I dislike Go, at least it appears to get this right.
gollark: It should be `int[10]* v` or something, so that the type information is ACTUALLY WITH THE TYPE.
gollark: That is total bees?
