Hello everyone. I just purchased a Crown Betta 2 days ago. At the moment, Im keeping him in a bowl with marbles and a plastic plant, but I'll definitely house him in a better environment of about 5gal, heater, filter, and more decorations very soon.
Ive never owned any fishes before, and dont know much about them, but Bettas look like a good place to start, plus I think they're wonderful fishes!
They're more interactive in my opinion, they dont just swim mindlessly like other fishes I always see.
I got some questions though about caring my Betta.
For water changes, Im doing 30-50% daily. I also use warm water because I know room temperature isnt enough to keep them warm. What I wanna know is do I need to condition the water again? Do I condition the new water only or condition the whole tank?
Hmm.. secondly, Im wondering is my Betta happy. He eats the Betta Pellets willingly, 2 times a day. Very active at times, swimming vigorously in the little bow. Iono if thats a good or bad sign. I notice he opens his mouth wide open sometimes as if hes yawning

. I dont see any air bubbles though, only the ones near the plant due to when I do water changes. He doesnt flare that much too when seeing other male Betta / Mirror. Is he just less aggressive, or something else? That pretty much sums up his behavior, hope people with more experience can tell me if hes doing ok.
I see a Crown Betta in the store with very big fins which I think it looks good, but the tips were curly so it didnt look so nice. I was wondering do the fins get bigger as they age, because my Betta's fins are kinda small at the moment, but then again he looks like a young Betta.
For tanks, Im looking at the eclipse system 3 by marineland with 3gal. It comes with a lot of stuff. A heater isnt included, but I already have my eyes on one. What you guys think of this housing? Its about $45, good price range for me.
Thats all the questions I have at the moment. Thanks for reading!
He isnt as big as the picture shows, its due to the water! I dont wanna make it look as if Im keeping a big fish in a tiny bowl with no where to go >_<. Its better than how pet stores house them :(.
