OK-I have been reading SO much about Guppies on here. Does everyone know that there are 2 different kinds? I read one thing about one kind and another about the other kind. OK-here it is: 'Fancy Guppies' have the pretty tails (males & females) and are larger than 'regular/Feeder Guppies'. 'Regular/Feeder Guppies' are smaller, are less colorful, but the males have reddish/orangish & black spots. I just wanted to clarify. Yes, I do have both-in my community tank! I just wanted, for awhile now, to clarify this, to avoid confusion in the future. (Maybe, I'm just venting, I don't know) But, different Guppies have different care/needs...and seem to me, to act differently, as well.
