guppy breeding

[crittergal]

can anyone tell me why my guppies are not breeding? I add fresh water to tank about every 3rd day approx 1-2 gal . I have approx 7 guppies per 10 gal tank. 5 females and 2 males in each tank. I feed 2 times daily. switch from flake to shrimp pellets and blood worms or brime shrimp (frozen) about once weekly. lots of covering for any babies to hid in also (live floating grass like plants) and still no babies. temp is 76 levels are all fine also. can any one give me any ideas of why thank you

How long have the tanks been established ? Are any pregnant ? What are your tank's parameters ?

 

[crittergal]

my tanks have been up for 8months to 1 year maybe alittle more . and my levels are at 0 ph at 7.6

Maybe they're too young ?

 

[crittergal]

my guppies are all at least six months and older

Try raising the temp if you can that should help.

All your levels are zero? That's strange. What are you testing your water with? Most cycled tanks will show some nitrates.
The filters in all of your tanks have been running for 8 months- 1 year?
