So on campus we have this huge fish tank (1000 gallons or so) stocked mostly with nano fish. Though I see something odd in it. There are these female guppies that are nearly 6". It's so weird. They aren't mollies or swordtails. It's strange, because you just see these male guppies come up next to them, about 1/5 of the size.
Why are they so big?
