Hmm... I'm assuming this is 5g+.
They like low filter flow, that's why I use sponge filters and internal filters with sponges blocking part of the flow. They need a heater which they like around 78*-82*F, it reminds them of Thailand
.
Mine LOVE plants, live plants more than fake plants. And if fake plants silk or fabric ones only because they don't like getting their tail caught. More plants the happier the betta IME.
Hiding places are a must. They love swimming in and out of hiding places, IMO it gives them a sense of privacy.
They like high quality food pellets, but only a few a day or else they'll get sick. They LOVE frozen and live foods, and the occasional dried food is ok.
They like love and attention, mine get all excited when I go near the tank. They swim around it like they're NASCAR drivers in Indy.
But the thing they love the most: clean water. They would rather have clean water more than anything else. It's what they live in and want the best for themselves.
Those are all based on my experience with bettas and a little based on some articles I've read
So, there might be some differences, especially since bettas have their own mind
Good luck with your betta
You won't regret getting one!
