I breed guppies (have been keeping them for 18 months), i have had quite a few fry, i have one big tank for my adult guppies and a smaller tank for fry, i let my females give bith in the tank, i then fish out the babies into a breeding net, when they are a week old i move them to the fry tank, as soon as they are bigger than the adult fishes mouths they go back into my big tank (as they grow quicker in a big tank) and then as soon as they get their colour i sell them, i rarely keep any of my own fry unless i get a very rare colour as i dont like then in-breeding.
I have never been over run with fry, the most i have had from one female is 20 fry (as some get eaten before i get to them), sometimes i only get 5 fry from one female. They dont produce fry every month (like people say), sometimes i go a couple months with no fry. I have about 5 adult females at the moment and i only have 10 fry (from 2 of my females).
Oh yes, if they've been in with males then they are pregnant for sure. Guppies make rabbits seem chaste in comparison
They can also store sperm for a short period of time so even if you buy a female from a tank of females it's no guarantee that you won't end up with babies- she could have been shipped with males or they could have been mixed up in the shop. Basically, if you're going to keep livebearers then expect babies.
Thanks. The orange one has one too, but its quite pink and doesn't show in pictures. I've been told if they've been in with the boys they're pregnant but I thought I'd ask here because the internet is a minefield of misinformation but MN has never steered me wrong!
It's pretty easy to tell females from males once you know what you're looking for. This is a line drawing rather than a photo so you can see it more clearly. The anal fin on a female is fan shaped and on a male is pointy.
Guppy breeding is brilliant fun for children and the babies are super-cute. As long as you've got homes lined up then go for it.
Yes they were sold as male. Looking at them it seems an easy mistake as one is very bright and the tail is the same as the other male her colour. I will try to take pics but they don't really like staying still! I only wanted males to avoid this but it's happened and my daughter is hoping for fry!
You could just keep the females in one tank and leave the fry in there with them. The weak ones may get picked off but plenty will survive, especially if you give them plenty of hiding places. Java moss is great for fry. If you're feeding flake food then make sure you crumble it up small enough for them to eat. Aside from that it's fairly simple!
If you're keeping a mixed shoal of guppies then you need to keep them at a ratio of 2 females to 1 male to prevent the females getting hassled too much. If you're not sure if they are male or female then can you get a photo?
Keeping 100 fry in 2.5 l with no heater or filter sounds like a pretty quick way to kill them
I finally got my fish. 6 guppies and a bristlenose pleco. I thought all the guppies were male but in my extremely inexpert opinion 2 are females and pregnant. I've got a second tank to put them into and am planning another tank after the fry are born to keep females separate. Thing is I'm confused about fry care. Websites give conflicting info even down to suggesting only putting 100 or so fry in 2.5 liters of water with no heater or filter. If anyone's actually had fry can you please tell me what you used? The shop offered to take them back but I expect the fry will get eaten in the shop, and having bought them I feel somewhat responsible for them!
