Guppy

No

They can have up to 30-50 fish, but mine only had one? Can anyone explain that?

No. This is overcrowded and you change the water every day? That will stress the fish out and the constant change of chemicals and temperature can harm the fish. Please do not continue this. When a few die do not get more. I suggest change the water once every 1-2 weeks. Whatever you do, do not continue this.

You should consider getting at least a 20 gallon tank, or re-homing some of the fish to avoid overcrowding your fish.

Male guppies are colorful and females are not. They are usually white or clear in color.

plants and rocks.

also shady areas.

No

Goldfish do not get pregnant. They are egg layers. Black spots on goldfish have nothing to do with their breeding condition.

No.

predators can easily spot them.

You do not say if the guppies are common guppies or fancy, also how many male and female guppies you have, yes as far as the snails and guppies go, one point to remember is the tank water should be above 72 degrees and some live floating plants for the guppies too hide in.

wipe it....(:

Because they are still newborn

They reproduce by mating.

There will be a dark spot in front of the fishes anus (cloaca) in a pregnant (gravid) female livebearer. This spot is called the "Gravid Spot".

It's not completely empty and you don't just leave it running. What you need to do is put it through the nitrogen cycle, which has no set time and can take anything from 2-6 weeks. It's this process that, afterwards, will mean there's lots of good nitrifying bacteria in the tank to keep the water quality healthy. Skip it and add fish straight away and you end up with a tank of dead fish!

There are tons of good websites on how to fishless cycle a tank. It involves a lot more than filling it with water and plugging it in, you need to add an ammonia producing source and test the water every day for ammonia/nitrites and nitrates.

Keeping fish is a bit of a chemistry experiment!

Because of the environment they live in.

This usually means that the fry have already been born. If the fry were born in the tank itself, you might not notice them at first, but they are probably hiding somewhere. If the fry were born in the breeding box and you don't see any now, the mother could have eaten them.

Profesor Hiralal Chaudhuri, the "Father of Induced Breeding", is considered as the father of blue revolution in India. See attached link for information about his book.

Female babies are born with a uterus, but it is not fully developed in the sense that it has not yet matured or undergone the hormonal changes associated with puberty. At birth, the uterus is small and immature, and it will grow and develop further during childhood and adolescence as a result of hormonal changes. By the time a girl reaches puberty, her uterus will be fully developed and capable of supporting potential pregnancy.

No, they are not.

If one is able to fit it into one's mouth and swallow it, yes.

Yes, I've found that if I turn off all the lights and make everything really quiet for about 20 minutes my guppies start to sleep in a school. They all stick together and swim around the tank its really cute.

The average is 28 days, although gestation can be prolonged by several months.

The gestation period can be affected by water conditions or other stress factors for the pregnant female. Severe stress can even cause the foeti to be aborted.

As guppies mature their colouring can change and the bright blues are often the last colours to show.

base on my research its yes
