If you wish to keep the fry you should put her in a different tank or use some kind of livebearer trap for her to have her young in.
All that is needed is a male guppy in with her.
it will have a red dot and black on its belly and will be fat
It is either in labor or is dying from an internal issue.
No, a guppy isn't a reptile. A guppy is a fish.
If it's a guppy and if it's pregnant, it might have it's babies soon.
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.
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 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.
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.
The signs of guppy breeding is when the males (the more colorful fish) start chasing the female guppies (the duller ones). The female guppies should appear to become fatter, signifying that the fish is pregnant.
