So, I am on a budget but have taken an interest in breeding guppies. Right now I have a 2.5 gallon fry tanka and a 5 gallon grow out tank. I was just thinking, could I breed guppies in Tupperware? I would hook up a air stone to the bins ~ 2 gallons each and change the water once a week. Only 2 fish per bin, until my garage gets cleaned out enough so I can shelve the aquariums. One last question- is it wrong to have hybrid guppies? My fry are 1/2 endlers livebearers.
