When pregnant, you do not get your period
A guppy fish is pregnant for about 4 weeks.
Mosquito fish are live-bearers; meaning they will have live free swimming fry. The mother will have a black spot on her belly near her vent, called the gravid spot, which will get larger as the fry are developing inside her. The vent itself will be a little open as she is about to birth. To maximize the amount of surviving fry, make sure to separate the mother into a specialized area where she cannot access the fry, nor the other fish as they will be eaten. Or have plenty of plants and other hiding places for the fry to hide in.
Well, despite the name, it is not an eel, but is a fish. Like other fish, they do not get pregnant and do not have a period of gestation. The female lays eggs, which are fertilized outside her body.
No they are not. If they're yellow for a long time they might be.
Guppy fish are pregnant for about 4 weeks before giving birth to their babies.
The female has a triangular anal fin. In the male this fin is elongated into a long point. This fin carries milt (sperm) like a penis and is called a "gonopodium".
When you are pregnant you will not have a period. You may have spottings though. Hope this helped :)
Mosquitos have a gestation period of 18-35 days long.
guppies stay pregnant for about a month before giving birth, other fish take longer, and others lay eggs (don't get pregnant). depends on the fish
Mosquito fish (Gambusia affinis) typically give birth to live young after a gestation period of about 21 to 30 days. The exact duration can vary based on environmental conditions such as temperature and food availability. A single female can produce several broods in a breeding season, with each brood containing anywhere from 20 to over 100 fry.
