Will any color neon tetra mate?

Neon tetras can mate, but their ability to do so is not determined by color; rather, it depends on the health and maturity of the fish. Mating usually occurs in a well-maintained environment with appropriate water conditions and a balanced diet. Both male and female neon tetras will exhibit specific behaviors and physical traits during the breeding process, such as the female becoming noticeably rounder with eggs. It's essential to have a suitable breeding setup to encourage successful mating.
