Sexual selection often is invoked to explain exaggerated ornamentation used in courtship displays. Such ornamentation requires greater resources and suggests greater fitness levels in males that develop it, perhaps as an indication of "good genes". We examined female choice in Betta splendens. Males are colorful, have elaborate courtship displays, and provide a resource (bubble nest) to a female's offspring. We varied male nest size and color to determine whether females choose males preferentially based on color, display, or next quality.
