bettasx - I agree upon no# 2 being the right one for your question. The betta has
no reproductive organ for transfering his sperm to the female. When he
wraps and kind of shivers, that's when he is releasing his sperm. When
the eggs come out, they are immediately fertilized and that can explain
how just about every single egg is fertilized. I mean the male must
release thousands of sperm cells compared to the few hundred that the
female releases. This is what I have learned and what others should really
consider applying to their betta breeding knowledge. Even the books
tell you that the bettas release sperm as the eggs fall. Well this is just
what I would know. If anyone has any other theories, share them.

Goh - A book which I read more than 20 years ago said
that when the male wrap around the body of the
female, his body is secreting sperm - at this
moment when the eggs come out of the female,
it will come into contact with the layer of
spermal secretion on its body, thus being
fertilized.

vinhthan - The male releases the sperm during the embrace at the same time the
eggs are released by the females. How do I know this? I finger-fight a
large male and gently grab his head, he will curl around my finger to
embrace just like he embrace the female. Look closely at the white dot
(that's where the reproductive opening is), you will see a very fine white
stream of sperm come out and it disperse very quick in the water. You
must use a very big male to see this. That big male must be aggressive
to fight with your finger.

Myron Tay - I believe it is largely (1), though the sperm is not 'injected' into the female per se but the genitals are aligned and sperm and eggs are released at the same time. I must add that this is largely true. Not sure if there is some variation in which the gentials are not aligned and (2) occurs?
Anyone?

BETTALOVA - I LITERALLY HAVE NO IDEA ON HOW THEY GET THOSE DARN'FORSAK'N EGGS FERTILIZED BUT I
WHOULD HAVE TO SAY THAT #2 SOUNDS PRETTY REASNABLE TO ME.

Hans - How are betta eggs being fertilized? I meant when in the mating process? I've come across different theories on this and am puzzled :-
1) the male injects the 'sperms' into the female during the curl-up process; their genitals align during this stage and that's where the eggs get fertilized and falls....
2) the male releases (sprays) a lot of sperms in the water during the process which in turn fertilizes the eggs as they falls.... (like how salmon fish does)
3) the male's bubblenest has sperms when it's built, such that any eggs being deposited on it will get fertilized; including those that are artificially
placed on top and transferred from another tank.
4) the male fertilized the eggs in his mouth, as he picks up from the floor....
Which is true?!? I get different answers when speaking to different people....

Snert - I think you can safely throw out number 3, as I know even the fallen
and "ignored" eggs are fertile. As far as # 4 goes, B. splendens is a
bubblenester, not a mouthbrooder. I don't think any fish has reproductive
organs in it's mouth, even if it is a mouthbrooder. Correct me if I'm
wrong, though.
I'm not sure about numbers 1 or 2, but my guess is that the male aligns
with the female and releases sperm into the water so that even when he
is away from the female, the sperm are still active around the eggs as
they fall. I doubt highly that he injects it into the female, as he
doesn't have an organ to do this like, say, a guppy or platy does.
