Sunbleak
Leucaspius delineatusAlso known as Belica, Moderlieschen, Motherless Minnow
Sunbleak are tiny, surface-dwelling carp relatives known for their bright silver scales that gleam in sunlight. They form dense shoals in calm, heavily vegetated ponds, lakes, and backwaters across Europe and Western Asia, feeding actively on tiny crustaceans and surface insects. Females wrap sticky bands of eggs in spiral ribbons around submerged plant stems, which males guard diligently until the fry hatch.
