I just have a quick question; how old do guppies start to breed? I've got a 4.5 month old batch and I'm just curious. I've heard you can tell the sex by about 6 months, is that correct? Thanks

Steady, you love that guppy girl don't you! That photo... lol
It depends more on physical size than on age - if their diet isn't adequate or they're growing really slowly, they might be well over six months before they are large enough to drop fry. Usually young females only have four or five - but imagine four or five newborn fry stuffed into her. Would they fit comfortably? If not she's probably not ready to have fry.
