I'm not quite sure I understand the whole "gasping for air" thing. My bowl isn't filled to the brim, so there is plenty of area at the top for mister Pinto Bean. Even if there wasn't, how would getting oxygen be any different? I've researches fish care, but before that video, I had never heard that it was any different getting oxygen from a bowl.
I disagree that all tanks need filters. If you monitor your water carefully, you can tackle problems at the start. it may be easier with a filter, but I don't feel as though they are necessary. As I said before, Pinto has been in his bowl for a year now, is perfectly happy, and blowing huge bubble nests. It may be better to move him into a larger tank, but nothing has really convinced me of that.
I agree larger tanks are fun. I have a five gallon with plants and flower pots galore.
My goldies have a 110 gallon tank. It takes up my whole room. XD
Fish take in oxygen from their gills, they can take it in though their mouth BUT if is goes to the stomach it can cause floating issues or swim bladder issues. You see this a lot with fancy goldfish since they use up a lot of oxygen they will gasp at the surface. Its kind of like when we eat or drink, if we do it too fast we get air in our stomach and that can be painful or lead to gas, and fish don't expel gas like we do. So it can be worse. Possibly messing up their swim bladder(the organ that controls balance int the water) and them floating all over the tank.
Tanks with a bigger surface area(the area where the water meets with air) have more oxygen in the water. Moving water puts oxygen into the water. Usually this is done by filters or air bubbles.
Do you have a liquid test kit that measures ammonia,nitrates and nitrites? How often do you test? How often do you do water changes and how much of the water?
Wish a fish with no source of filtration you should be doing daily water changes since there is no place for the bacteria to grow and colonize and break down the waste. It can grow in the gravel, but that is a double edged sword since waste and food can build up there and poison the water. Plus, not a lot of bacteria will grow on gravel.
If you are an
experienced keeper it can be done without a filter(with daily water changes or lots of plants). But if you had to go out of town for a week you could not change out the water for it to be safe, and since it takes about a month for a filter to be colonized you could easily lose a fish.
Not a lot of fish keepers are willing to do daily water changes or monitor the water chemistry closely like others would be so it is better to have a filter, not only that but like I said. If you had to leave the fish for a while you would have to worry about his waste building up. With a filter you dont have to worry about it as much. Also having a filter will be able to catch ammonia spikes and break down the waste even before you know what has happened.
A fish living in a tank with no filter and not frequent enough water changes is like us living in a bathroom without flushing the toilet but still using it, you have to eat and sleep there, only flushing the toilet when you clean the bowl. Its nasty and not only can you get very sick from it you can die from the bacteria from your waste if you live in it for long. Its the same for fish or any animal.
I hope I don't offend you by saying this but as fish keepers it is our responsibility to make sure that no matter what happens our fish are safe. This means going the extra mile and having a backup plan, since they cant run away when they are in pain or have no way of saying "this hurts". And as much as I hate to admit it, we cant speak to our fish(even though I still do) and ask them if everything is ok. So we truly don't know if something is wrong, the only way to be sure is to walk on the side of caution and provide optimal living conditions. You don't have to have fancy gadgets, a small sponge filter that costs under 15 bucks that you can make would be good and VERY beneficial to his health, as even just a week of being in .25 ammonia can be deadly if the conditions are right.
My tank just went through a cycle bump, my PH is 8.2 and the higher P.H you have the more deadly ammonia,nitrates and nitrites are. I lost one fish from a mix of gasping/swim bladder issues ,ammonia,dropsy and getting stuck to the intake because she was so weak.
Good filtration and clean water is a necessity in this hobby. Filtration= good, clean water and good,clean water = a healthy fish that will live a long time.

Edit: New species of betta has been found in Thailand and ohmyfins is he gorgeous. I suggest a field trip to go get it!!
