Betta Fish: My first baby

Hi
I’m new to fishkeeping and this is my first son, Marvolo 💙

I did a full fishless cycle before adding him, and he’s been with me for 2 days now.
He’s exploring the tank, resting on plants, and interacting a lot with his surroundings.

Based on this video, does he look happy and comfortable to you?
I’m still learning, so I’d really appreciate any feedback or tips! But please, be kind!

Tank specs:
• 30×30×30 cm (≈28 L / ~7.4 gal)
• Filter running 24/7
• Light on for ~7 hours a day
• Heater currently off due to hot weather (stable at ~28 °C / 82 °F)
• Added a small piece of sponge to the filter to soften the flow, he actually hangs out near it a lot.

FYI: You’ll see him jumping out of his floating house — he wasn’t stuck at all! There’s an opening and he goes in and out on his own.
And I’m planning on adding more plants!
