They can come either as male or female.
Boom. Eye Gone! O_-
usually bu thier looks. Some can be told by thier eye color or skin color.
Angler fish have a bioluminescent lure called an "esca" on top of their heads that attracts prey. When the prey comes close, the angler fish uses its huge mouth and sharp teeth to quickly snap and catch its prey. They are ambush predators, relying on patience and the element of surprise to catch their prey.
There is no specific research that I am aware of to indicate a dimorphism between male and female fish scales. Certainly there is no obvious difference that can be seen by the human eye.
no they do not, they evolved to the point that with a simple look in the eye from an alpha male goldfish it can inpregnate not only female gold fish but the male gold fish too. this has been caused by centuries of evolution.

She will have a tummy that is rounded as if a tiny ball is inside her. If you keep an eye on them when you put them together you will soon see if she is interested and ready by her behaviour.

ZERO!! A 1 gallon tank is not large enough to keep any kind of fish in. A Bubble eye goldfish can grow to 10 inches long and so, using the basic rule for keeping fish. "1 inch of fish need a minimum of 1 gallon of water" you would need at least a 12 gallon tank to house 1 Bubble eyed goldfish.
its where the male mate of the sex party climaxes in the female's eye and the female regurgitates it threw her mouth
no both have blue eye sacks the male has brownish blak eyes and the female red
The male Betta is beautiful with a flowing back fin,with bright and eye-catching colors, and they are bigger than the female bettas.But the female Betta doesnt have flowing fins and they dont have bright colors,but the brightest color you can probably get is orange and i think white for the female.
