Is he black and clear. His so beautiful.

I thought 2.5 gallon WAS the min. Now people are saying 5 gallon and others are saying 10 gallon. Whats next 20 gallon min for one betta? I'm sure he'll be super happy but really guys? I think as long as the fish keeper know what they're doing then it shouldn't matter compare to someone who has everything but can't keep the fish lasting long.

Where's the filter? Where's the heater?

I would add a apple snail or a few more plants to keep the tank clean.

Where did you get the 4 gallon bowl from?

Yeah, this is NOT how you set up a betta tank. You need a 5gal or bigger tank with a filter, heater, and airstone or bubbler. The decor is up to you, I would avoid some decor plants because they can tear up fins. I would use silk plants or real plants. Never use bowls or small tanks less than 5 gallon. Having a bowl has many cons than pros, and specially for bettas because they can be exposed to a lot of diseases and illnesses.

pisses me off that people think they know more about keeping betta fishes, shut up enjoy the video, at least its not stuck in that cup

Can u subscribe to me pls

some info to some betta friends and keepers~
-a lot of betta keepers and breeders due tend to keep betta without filters (some traditional breeders dont have electrical outlet)
due to the fact they can change their water often every 2-3 days depending on stocking levels and size of container
-tap water (De-clorinated) usually can come around 7.5 PH (in certain places) which make ammonia quite toxic, so water change happens way too often (usually everyday), lower PH means ammonia is less likely to harm bettas. this is achievable by breeders and keepers by adding plant matter. The best and cheapest kind are indian almond leaves which lowers PH by a significant amount (a.k.a poor man's water conditioner), driftwood and other filtration such as peat moss helps.
-filter with low flows are for those that want to keep betta but doesnt change their water as much often, if you are feeling lazy go look up some HoB filters they usually comes with some flow controls (looks like a plastic screw)
-betta can get along with other small fishes like neon tetras (they love still water), however bettas have different personality so be sure to monitor if anything happens. in planted tanks I neon and betta makes wonderful viewing experience.
-guppies dont work well, some males does represent flowy tails that makes betta thinks its another one of its kind.
-heater is either optional or necessity, depending on your household/place you live in. usually on warmer climates and room temp betta will do just fine indoors, but on cooler temps and winter season you may need to give the cute betta some a good heater. if temperature fluctuates way too often and difficult to control. go get a heater~
-betta is a fighting fish and bred to fight with each other (that's why they called it a fighting fish) but nowadays it becomes a beautiful display fish as it goes on (however ashamed that its living condition hasnt improve until now)
in the era of fighting fishes, cattapa or indian almond leaves are used to strengthen their scales and relieve stress after fighting as medication (extract works best). rumor has it also enhances color and brightens their color (achievable by good lighting and heavily planted tanks).
-betta like most prefer security, planted tanks in secluded places from loud noises with calm atmosphere can help them grow and live longer. (hiding places such as broad leaves on plants provide excellent place to sleep on, floating plants gives shelter for bettas)

(edit)
sorry for the TL:DR comment~

Are the thriving plants what keep the water free of ammonia/nitrite? You can achieve calm, stress-free water for a betta fish without going filter-free. I don't know the details of your set up but the betta breeders I know all keep filters (usually sponge)... I know you don't like being criticised, but it's going to happen when you have a filterless bowl with a betta in it... when you have are a pro goldfish keeper. This just surprises me. I am a fan of your channel, so don't take this as an attack.

How often do you do waterchanges for this tank? It is my first time i heard of not using a filter so i am curious to know how you keep this tank stable :) Thank you in advance!

You shouldn't be using your hands to catch the betta, & don't use bowls, it isn't enough space for the betta…

Bettas do need filters. Look it up

doesnt he get a heater ? :(

Did you put water conditioner in the tank first?
