lol, theyll breed in just about any sort of conditions wiht in reason!
there hardy little fish!
but if you want to line breed them your gonna need more than one tank!
i suggest you start of by getting some good stock!
once you've dont that deside what you intend to do with them?
wether it be linebreeding as i said before or hobby breed them? or jst have them as decoration fish and occasionally catch some of the offspring in the tank to grow to adults!
Ideal conditions for them:
brackish water
heavily planted tanks
1x male to 4x females (the only thing on a male guppies mind is breeding and you need to share the stress of that round the females)
do not worry about breeding them it seems to come with the territory when owning guppies, they will do it of there own accord
some people migth have had different experiences, but my guppies give birth every 4 weeks on the dot! to broods of between 50-150 generally
dont jump into it and buy the miserable crappy things at pet stores, its not worth trying to breed those as they are what i would call (feeders) make sure you do your research and find som1 who has high qaulity guppies!
if there are anymore questions just ask, please make them more spesific as it makes them easier for me and othere to answer!
