Thanks for all the helpful information on the guppies. I have had more males born in lower tank temp. Like 72 degrees or lower. The temp higher will Produce more females this is true. I have a friend that tells me she always has more females them males. I told her to lower the temp. to get more males. She told me that over the spring and summer her fish room never get lower then 80 degrees. All the tanks and the lights over the tank produce heat. I keep all my tanks at 72 degrees.

Thanks for the info :)
i'm not really wanting a particular strain, just hardy and pretty fish. Do you keep your groups of one male and his females separate then to ensure you know they are his offspring?

There are different methods of breeding, if you want very predictable results then it's best to keep each individual male with a small group of females (2-4). You can also keep a community of Fish where there are males, females and babies all in one group, it's harder to predict results but it's certainly less labour intensive and you don't need as many tanks.

The difficult bit with breeding Guppies is trying to limit the number of tanks, many serious breeders end up with literally dozens if not hundreds of tanks.

I would try to establish a set aim before you start so you don't end up with trying to do everything and end up achieving nothing. I would recommend this strain, it enables you to cross strains without getting into complicated genetics and you can always find easily available and genetically different Fish to out-cross with without having to go 'back to the drawing board'.

Ooh I just bought a dragon head male at the weekend!! I got 8 guppies in total, 3 males, 5 females, planning to get more females when I see some I like. I've just bought a few different strains, I guess I'll see what happens for now. I will be keeping them all in the same tank, I've already got 4 tanks running and a spare in the cellar lol, no room for any more atm!! But plenty of spare space for babies as I've barely got anything in my other tanks.
I have always had a massively high death rate with my guppy fry, how do you find yours??

I wouldn't worry too much about a high death rate, the healthiest ones will survive.

One thing to be careful of is that they can be particularly sensitive of chlorine, the effected one's heads will move from side to side when they swim and will look like they're struggling to swim. When I do a water change I normally add a dechlorinator and then use an air stone on the water for a few hours before I put it in the tank.

Other than that just treat them like any other Fish and give them a decent planted area, given a few generations you should find you're getting a better survival rate, the ones that die/get eaten are just the weaker ones, as happens in nature.

Yes I always use dechlorinator in my tanks. I have an air pump running most of the time as well for extra oxygen as I have some new bristlenose catfish fry in there as well ATM.

Need to get some more plants, I'm going to cover the bottom with large polished river stones so that should provide plenty of hiding places for the guppy fry :D is it safe to put in the polished river stones (I got them in Morrisons but haven't added them yet as I'm still washing them and the water seems to have grease floating on it??)

Sorry, I should have been more clear. I meant that alot of dechlorinators take up to twelve hours to neutralise/remove all the chlorine in tap water and because Guppy fry can be so sensitive to it I add the dechlorinator and then run an air pump through it for a few hours to make sure it's done it's job properly.

I'm not sure about the stones but if there's a film on the water it doesn't sound good, maybe there's a residue of some chemicals they treat/clean them with???? If so I wouldn't add them whilst you're still getting a film on the water.
