The female guppy will develop a dark spot on the side of her belly during pregnancy. As the pregnancy progresses, the spot will grow darker.
All that is needed is a male guppy in with her.
The Gravid female will have the dark "gravid spot" in front of her vent. I can however assure you that if there has been a male in the same tank with a female guppy for any reasonable length of time she will be gravid.
With a guppy you need to look at the gravid spot. This is a dark spot in the fish's belly. A large gravid spot indicates the fish is likely to be pregnant. You can tell how pregnant the fish is by how large the spot is. Sorry I have no experience with other species.
it will have a red dot and black on its belly and will be fat
When your female guppy is pregnant you can't tell by it's size. You have to look at it's gravid spot. Which is right behind their stomach and the tail. It's right around the butt of the guppy. It takes about a month for the babies to be born. Plus you can not stress out your the pregnant fish.
It is either in labor or is dying from an internal issue.
No, a guppy isn't a reptile. A guppy is a fish.
A female guppy is pregnant for about 1-2 months, if you have a pregnant guppy i can tell that she will need to be separated from the other fish in a breeding box, you can buy breeding boxes from most stores for £3.97 ($5.97), because if she is left with other fish they will eat the babies. Some tell tale signs that she is close to delivering the babies is that she will stop eating, hang around away from the other fish and her gravid spot will be almost black. Pleased to help.
If it's a guppy and if it's pregnant, it might have it's babies soon.
Hi There are fish concepts used in the aircraft industry. The Aero Space liner The Super Guppy B377-SG/SGT wide bodied cargo Aircraft was the successor to the Pregnant Guppy. Five Super Guppy's were made. The Guppy (Poecilia Reticulata) is a Tropical Fish and is quite easy to keep, and they bred easily.
The female gets a deeper tummy and there is a dark (gravid) spot by her anal fin.
Robert John Lechmere Guppy did not invent anything. He is most known for having discovered the guppy fish. The guppy fish is named after him.
