Yup. Bettas usually will make their nests on a clump of plants or leaves in the wild. They don't usually stray from the nest.
When a male with a nest and a female who's ready to breed meet the usually begin courtship. My most recent breed, they got right into spawning.
Who am I? Well I am a Junior Member of the International Betta Congress and a breeder of white HMPKs, red dragon HMPKs, black/red dragon HMPKs, metallic multi HMPKs, blue masked HMPKs, and now multi color HMs. Soon to add black HMs. I will be showing in New Breeder class in fall of 2012.
