Well I have one female, one male guppy, and 2 koi in my tank. I got my guppies about a month or so. I was thinking if my female guppy is pregnant because it has little black on her gravid spot. And i put her into the topfin breeder net to separate her from other fishes so that they fries can be safe when she drops the fries. Should I do that or should i just leave her in the tank with other fishes and move her into the topfin breeder net when I see her dropping fries? What should i do? Please help me. I'd be really appreciated :D Anyways now I put my female guppy back into the tank. Will guppies breed with koi in my tank? Will they breed with any other fishes in my tank? Here is the link of my guppy --->

Looks about 1-2 weeks pregnant to me, at 1:17ish she turns sideways and some nice light shines on her and you can tell. At about 57 seconds on the video it looks like a comet goldfish swims into the corner of the tank then back down, pretty sure thats not a Koi.

Welcome to the site.

She is a big Guppy, but doesn't look pregnant to me. Hard to see the gravid spot. Guppy will not breed with Koi, in fact they shouldn't be in the tank together. Koi get very large...I hope this is a big tank.

This is my biggest female about 4 days before she had fry

Hello and Welcome to the forum. She sure does look like she will be having some little ones soon.

Will she have babies in the same tank with goldfishes? Cuz I dont have another tank and my tank is 10 gallon. I only have the breeder box. Should I put her back in there?

Don't put her in the breeder box yet. She is not close enough to having babies, you will just put stress on her and do her harm. She can have babies in the tank, but the goldfish will most likely eat all of the fry. Wait another week and take another picture of her and post it. To tell for sure if she will have babies soon.

Okie

How long it takes guppy to breed by the way?

a male can breed with a female anytime after each of them are atleast 3 months old. But it usually takes 28 days for the female to give birth, plus or minus 2 days usually.

no I just feed her flakes.

I am afraid she will have babies while I am sleeping at night. When I woke up all the babies will be gone =.= I only have one tank. I am keeping an eye on her though. Sometimes she is quiet in the corner or in the house. And the male is mostly with her. I'd say always ^^

She isnt close yet, a minimum of 1 week left til she pops, but id say 2 weeks. Try adding another bushy plant, you have some nice hiding places, but i think one more bushy plant will help for hiding the babies. Most of my guppies give birth during the evening, once all the other fish start calming down for the night. How big is that tank? A 5 or 10 gallon?
