why dont i ever get any male guppies?

Question

hi i have about 20 guppy fry and they are about a month or so and they all have colours and they are still really small they are by themselves in a 15 gallon tank and whenever i look at them they are all female. they are starting to get a round tail but some of them are really colourful e.g half black body with bright blue fins. will some of them be males or is it that they are all females

they are fed 4 times a day 25 degrees water cleaned every month or so

Answer 1

Well, if you would keep up with more watermaintanance they would grow a bit faster and be healthier
I'm positive that you have for sure some males in that bunch

But please do weekly partial waterchanges of 25% and not once a month or even less

Here is an article which should help you to be able to sex them

Answer 2

You should do some small water changes 1x a week. Any ammonia in the water can stunt or slow the growth of guppy fry.

Guppy males don't really color in all the way till they are 4-6 months old.

Answer 3

after one impregnation the female can have 4 or 5 batches of fry
it's a long time since we kept guppies I can not remember when the male colours came in

Answer 4

Depends. You can't look at the tail to see if they are male or not. Look to see if there is any gonopodium on the male. The males have pointy one and the female have round ones. Second, all your babies could ba hybrids. If you have a platy or guppy the could mate and have lots of hybrid babies, all female.

Answer 5

The reason they are so small is most likely due to poor water quality! Feeding 4x a day & only changing water once a month can lead to disastrous results!
