7 Guppy Breeds
Aren't these guppies beautiful! They are all males, (I think they are all males) but notice how the guppy on the right in the middle row has more of a female guppy body outline. See how the male on the right in the bottom row has the classical male guppy streamline shape?
Look at the nice healthy eyes on the bottom two. A normal eye has that whitish ring with a black or red center. Guppies can get a condition where the eye will change, and all of it will grow dark and bulge forward like a pug dog's eyes.
Some people will try to tell you that a bulgy solid eye is normal. The fish seem to swim and feed okay, they don't appear blind, but it doesn't look normal. The fancy guppies that I had seemed to catch it, but the wild type I later got did not. One guy that sold fish said it was a disease that the wild type were resistant to, but some of the fancy types were susceptible to. The red eyed fish (partial albinos) seemed resistant too, but not always.
Most pet shop people act like they can't tell the difference between a guppy with normal eyes and one whose eyes are going bad. If it is a disease, I don't want it in my fish tank in my house. and if it is not a disease, why does it look like that? Look at the eyes on the bottom two guppies, I will only by guppies with good eyes like that.
The bottom two guppies are short tails, the short tailed guppies that I had lived much longer, and didn't mope about the tank getting sick after a few months, they remained healthy, and vigorous; I liked them better than the long tails. My mother liked the long tails. To each their own. Not everybody likes the same variety of guppy - if they did, then breeders would only produce that one type.
