If I could have pics of ammonia tests or scientific sources please!
Here you go, friend!

Scientific and authority resources outside of Tumblr for people that just won’t take experienced fishkeeping hobbyists’ word for it:
- Your Duty of Care for Keeping Fish Under the Animal Welfare Act
- The Siamese Fighting Fish
- RSCPA: Siamese Fighting Fish
- Ornamental Fish Association
- Betta Splendens
In at least one of the above scientific and authority resources outside of Tumblr, it’s specifically stated that bettas should not be kept in anything less than 2.5 gallons.
I hope this will help. Just keep in mind that many ignorant people will just go all TL;DR no matter what you provide.
