OKay so I though of getting a 30 gallon tank with guppies but I don't know how many guppies to get..and I've been getting all these different opinions and it's getting me confused
 
30 guppies would be about the maximum unless you wanna do really regular water changes.
 
Its easy for every 5 guppies you will need approx 1 gal of water. It goes this way according to the calculation. The fish is approx. 1.5"long x .25" wide x .50 high = .1875 gals per fish x 5 fish =.9375 gals or approx 1gal per 5 fish. Multiply 5fish /gal x 30 gals =150 guppies. But if it were me i wouldn't put that many in one tank just to be safe. This depends on how well you maintain your tank, how much you feed, the type/amount of filtration etc. At 5 guppies per gal you would be maxing out your tank, and really dont want to do that.
 
One pair will more than fill that 30 gallon.
 
I would do two males and six females. They'll likely reproduce and then there will be fry as well, want to make sure there is space for them.
 
yeah, it really doesn't matter how many you start off with. . . . eventually the tank will have more guppies than water, especially if it is well-planted with a lot of hiding places for fry. if it was up to me, i would start out with 3 males and 7-8 females. that way there is some variety in the bloodline and everyone won't be inbred right away. it gives room to add more adults, without there being so many adults that the fry get eaten right away.

my experience with guppies - 30g guppy tank, also short-term grow out for a black ghost knife. he ate all the fry, and all the males (slow and easy to catch). we moved the bgk into another tank in mid-september. since then, the 8 females that were left have produced maybe 300 fry. . . . probably about 175-200 of them are swimming around in the tank in various stages of growth. kinda ridiculous, but female guppies can have several spawns from mating just once. it's mid-november, no males in the tank since maybe mid-august, and 4 out of 8 have babies on the way again.
