Now, I am going to explain the Guppies tails, and how they use the bathroom. I KNOW WHAT YOU'RE THINKING, BUT HEAR ME OUT!
A Guppy's tail functions somewhat like a pair of pants. It is in fact an article of clothing, but unlike most clothes, it can be worn all the time. Whenever a Guppy has to use the bathroom, they can simply pull it down, and for boy Guppies, there is a slit in the front that acts as a sort of zipper, and can be opened for convenience.
The tail cover covers the Guppy's actual tail and *private parts*. The actual tail is a solid color, with the tail fin being a lighter shade of that color. For example, Molly's under tail is blue, and her tail fin is light blue.
It should be noted that just like humans, Guppies also wear underwear underneath the tail cover. Obviously, a Guppy's underwear is a bit different than a human's, as a Guppy's underwear has one hole instead of two, and is slid on somewhat like a sock.
I hope I have explained this well.
