Sure! I'll just randomly rant here and add stuff, feel free to take points and add them and change them to suit your speech!
-Although bettas are advertised as beginner pets for children, there are many aspects of their care that employees fail to mention to new owners
-Betta fish come from Thailand where the water is warm. If you've ever heard that they live in puddles, this is only half true; the dry season in Thailand is so severe, the huge rice paddies they inhabit will sometimes dry out until there are only small puddles and waterways left. Thanks to the Betta's labyrinth organ, it can survive in these conditions because of it's ability to breath air from the surface. After the dry season is over, those betta who survive the drought will be able to swim free as rain adds precious clean water to their homes.
-Now, even though they may be able to survive in those small waterways for a short time, a bowl has even more disadvantages many do not consider. In the wild, the plants and earth in the ecosystem will absorb all of the unhealthy ammonia and decaying matter from the water and adds healthy nutrients, so even in a stagnant pond, the water may replenish itself. A bowl made of glass does not have this ability, so the harsh ammonia that burns the gils of the betta is trapped in with the fish.
-Because bettas are in captivity, it is our job to replicate the environment they are suited for, seeing as we have taken them away from nature. Water in an air conditioned house is simply too cold, so most betta fish owners need an aquarium heater, which only function properly in at least 2.5 gallons of water. Additionally, water changes are necessary to simulate how the earth removes the harsh, toxic chemicals from the water and replaces it with good nutrients. Depending on how big the tank is depends on how often and how big water changes should be.
Blah blah blah, blah blah blah, that's pretty much it.
I guess another point is bettas are not like their wild cousins, they were developed in captivity and are more sensitive than the wild ones.
I guess here are some shortened points
1. To properly keep betta fish we must first examine how they live in their wild environment
2. In the wild they have warm water, plenty of room to swim, and nature itself cleaning up the waterways
-the proper temperature for their water is 76-82 degrees.
-In droughts it is true that a betta's water may shrink to the size of a small puddle. They can survive this, but only for a few weeks, until the water rises again or the fish perishes.
3. When placing a betta in an artificial environment, it is our job to replicate their natural environment
-that means getting a working heater to keep the temps up
-that means changing the water to remove ammonia
-that means giving them room to swim
You know, whatever, all that stuff
I know all of this is random and silly, but this is sort of just in brainstormy format, which is where I just blah blah blah all over a page and figure out what I really want to say, LOL.. I hope at least something here sticks out and helps
