Breeding Black Widow Tetras

[hadjici2]

Hello,

because I have a really fat black widow tetra, it came to my mind that it might be pregnant and ready to lay eggs. It has been 2 weeks though and no eggs since it is still fat and so I guess that it is just fat and not pregnant. I realy like these fish though and I would like to breed them. I didn't find much information on breeding these fish so can anyone tell me how?

How do I distinguish males from females....I know its something about the fins but a picture will be most helpful....at least if someone can find a picture on the net and just say that this picture is of a female or a male.


Thanks.

Female black widows are generally larger than the males and have a rounder body. In the female the anal fin runs parallel with the vertical black stripe in her abdomen. Males are smaller, have a broader anal fin, and a narrower more pointed dorsal fin. Males occasionally have white spots on the caudal fin.
Larger males will generally claim a territory that they will guard during spawning periods. Although they are egg scatters they prefer to spawn among fine-leaved plants, which should be provided in the breeding tank. Once spawning has occurred the parents should be removed, as they will consume the eggs. Eggs will hatch after approximately one day. The fry may be fed freshly hatched brine shrimp, egg yolk, or finely ground flake foods.

But how do I know that they are ready to spawn? I mean do I see the female fat and round and that means that she is ready to spawn with a male? When do I know to move them to a small tank so they can spawn....
