Domestic Angelfish

Hobbyists have been keeping angelfish for nearly a 100 years, but it wasn't until 1953 that the first color mutation occurred. Since then, many more color mutations have been developed. Today, there are dozens of phenotypes to choose from.

In some phenotypes, the genotype has not quite been figured out yet. Two genes are considered obsolete or lost to the hobby. However, these genes "are" recessive and may possibly be hiding behind dominant genes. All we know about these genes is from Dr. Norton's research, and there is very little information.

Other mutations have occurred such as Philippine Blue (pb/pb) which is a recessive gene and appears to be located on its own locus. Although it is obvious that this gene exists, the actual test crosses have not been resolved and is still in development.
