Gender
The male Black Phantom Tetras have longer fins than the females and when in breeding condition, the females become plumper, but the biggest difference is in their color. The males have almost no red, while the smaller fins of the female both on the top and underneath them are red. The adipose fin, on the top of the body behind the larger dorsal fin is much more noticeable in the females than the males, because in females it is red while in the males it is grey. The female's dorsal fin has a more intense black than the male's. When the fish are in breeding condition, the colours of both sexes become more distinct, with the male showing its black fins more obviously.

Famous quotes containing the word gender:
“Most women of [the WW II] generation have but one image of good motherhood—the one their mothers embodied. . . . Anything done “for the sake of the children” justified, even ennobled the mother’s role. Motherhood was tantamount to martyrdom during that unique era when children were gods. Those who appeared to put their own needs first were castigated and shunned—the ultimate damnation for a gender trained to be wholly dependent on the acceptance and praise of others.”
—Melinda M. Marshall (20th century)
“But there, where I have garnered up my heart,
Where either I must live or bear no life;
The fountain from the which my current runs
Or else dries up: to be discarded thence,
Or keep it as a cistern for foul toads
To knot and gender in!”
—William Shakespeare (1564–1616)
“... lynching was ... a woman’s issue: it had as much to do with ideas of gender as it had with race.”
—Paula Giddings (b. 1948)
