A good upbringing can make you more attractive to females – if you are a mosquito fish, that is. Researchers from the ACT have shown that female mosquito fish prefer males who had a solid nutritional upbringing, even if the males are superficially identical to their poorly-fed brothers.
“Males similar in body size, but differing in developmental history, are not equally attractive to females.”
