This is me giving you a mega download of all the basics of betta-keeping in thirty minutes. I probably cover 90% of what you need to know to keep for bettas, which is more than enough to get you started.
Bettas are a great beginner fish for people just entering the hobby and I highly recommend them. I’ll probably keep a betta in some form or fashion until the day I die because they’re that cool and personable and fun.
