Wild betta smaragdina hybrid
Two smaragdina Hybrid males, these two are siblings. Only one has a copper coloration due to it having an extra metallic gene. Both are Homozygous for Iridescence but only one homozygous for metallic (the copper one). This shows how a small difference in genetics can cause a significant change in coloration.
