Ovipositor - The reproductive organ through which a female fish deposits her eggs. In some fish this is always visible, as in the female Betta splendens where it appears as a small white bump at the base of the abdomen. ...
· Ovipositor = a special organ of some specific fishes (i.e. bitterlings), found on ♀♀, which is the extension of the genital papilla and used to deposit their eggs into mussels when spawning ...
Female has small ovipositor at breeding time, and drops large eggs near the surface. Thick plants like Myriophyllum catch many of them before the breeders can gobble them up.
Not a seasonal killifish. Is easy to maintain in the aquarium.
These look like little nipple-like projections and are called ovipositors (oh vi poz' uh turs), a word that literally means "egg-placer(s)". The female's ovipositor is larger and more blunt than the male's which is slender and more pointed.
Meanwhile the female should also be fed lot's of food until she looks as fat as the female in the picture on the right, in which you can clearly see the white ovipositor.
The female has a visible ovipositor two to three days prior to egg laying. From 150-200 eggs are laid in snail shells, under rocks and roots, and in crevices. The eggs hatch in 4-5 days and the male guards the brood.
Soon the pair should begin to show interest in the slate strip and the female's spawning tube (ovipositor) will begin to descend. This is the signal for you to prepare for the most important part: artificial hatching and rearing of the fry.
Examination of the ovipositor can sometimes also indicate sex with the female displaying a larger, rounder appearance to pass eggs through, while the male displays a more pointed appearance; this may only be evident when the fish is ready to spawn.
The female has a short ovipositor. They will form lasting pairs and make a nuclear family. The fry are usually well cared for, but the parents may eat some of them.
Their entire abdominal region becomes a cherry red color and they develop a very prominent ovipositor. They are typical cave spawners and both parents will often participate in care of the young. The young are fairly robust and grow rather quickly.
The female will sport an ovipositor, a small nipple on her belly, that will become larger as the actual spawning draws closer. These fish choose a flat stone, usually in a cave as the spawning location.
The pair will choose a spawning site and begin cleaning it with their teeth. Their ovipositors will be visible, which means this is the earliest chance we have to reliably sex the pair.
Males have vivid colours and (usually) much larger fins. Females may also show an ovipositor, which may be useful for sexing short finned or wild bettas.
Breeding: ...
Egg Spot
Mature females will display an "egg spot" between the ventral and anal fins. This is actually the ovipositor, which is used to lay the eggs. Males will rarely show an egg spot.
Males are more intensely colored and might have longer fins while the females will be a browner in color however females should display an ovipositor or egg tube.
Reproduction ...
Spawning begins when the female swims over the cleaned rocks and deposits the eggs in small lines through the ovipositor, and then the male follows her and fertilises them.
For my Bettas it usually takes about 1 week, you can tell the female is ready when a white dot appears behind her ventral fin this is the end of her ovipositor tube where the eggs come out. The male will have then finished the bubble nest.
How about an > ovipositor plug? > > I guess I will have to decide which to get rid of... ugghhhhh.
