I kept all my bettas in fully filtered, heated and cycled tropical tanks, most lived 3-4 years despite many being rescues. i personally wouldn't dream of keeping them in unheated unfiltered tanks.

thoughts? i see many bowls on here and it does grate me a little that such things are even sold in pet stores (fyi they're illegal in italy, the only country to care about fish care?).

I personally think that the absolute minimum for a betta tank is 2 gallons. Unless of course it is just a quarantine tank.

I also keep my bettas in fully heated and filtered tanks. It should be no other way. :)

I do know some people who keep their fish in tanks but use a small flat-sided bowl for photographs because it's easier...

But yeah I agree. I have two (on male/one female) in a divided tank (10 US gal) and one male in a 6 US gal tank that is long and shallow (22 inches long), all with filters and heaters and live plants...can't imagine putting them in something smaller as they love exploring and playing in the bubbles/plants/current.

My betta is in a 2.5 gallon tank by himself, with hiding places, lighting, and heating (I actually managed to find one small enough to not overheat the tank), and I don't have a filter, but I clean it thoroughly every few days as soon as the parameters start to go up, and feed hikari pellets that don't go to waste.

My betta is in a ten gallon tank with other fish. He loves swimming around in all that space, and actually gets along very well with the right kinds of fish.
why is it that people think it is ok to keep bettas in tiny tanks?? is it because you think that they live in puddles? the actualy live in rice paddys that are thousands of gallons in volume. whay do people insist on keeping bettas in tanks of less than 10 gallons. and the pics of your bettas in wine glasses is just wrong they barly have enough room to turn letalone swim. look at the condition of a betta with enough room to swim and one kept in a tiny container look at the muscle mass and the shape of the fins a betta should be able to hold his fins fully erect when angered and not have them drop to the side or ground. my betta is in a 12 gallon tank with just a few corydoras pygmaytus.

a lot of people think it is ok for those tiny bowls because the pet stores display them in those and have a lot of small bowl merchandise near them for a cheap price. if you ask the store employees a lot of the time they recommend those small setups for bettas. which all leads to people thinking its ok to house a betta like that.
i know it anoys the hell out of me. most respectable stores only use the betta barracs to help preserve the fish's fins during the day to day catching of the other fish also if they are short of space and have to put them in display tanks with more aggressive tanks. a topic close to my heart

I have kept bettas in unfltered tanks but never unheated - plus I'm pretty fanatical about water changes every 3 days in a 2.5 gallon.

I keep all my bettas in filtered tanks - I just hjappen to see one want it then buy it and dont have a tank ready for it! so it goes into the betta hotel for a few days until I can setup a new tank! :D

I've got my tangerine-colored male betta in a 6 gallon, heated, filtered tank with his african dwarf frog buddy. He seems very happy, if the bubble nests are any indication. I've kept bettas for years and never in anything smaller than 2 gallons. They just look happier with space to stretch those gorgeous fins :D

I have mine in a 10 gallon tank with hides and heating, but no filter. Before, I did put in a filter but my betta's fins kept getting sucked onto the tube, so I just gave up. I just make sure to change his water frequently, which I don't really mind. I hope people would ditch the bowls because bettas do swim a lot.
10 gallons is a good size for a betta splendens though it should be filtered if your fish gets stuck to the side fo the filter then the filter is far too strong but you should have a good water turn over to keep it oxyginated and low in toxins which will burn the gills and fins, they will breath from the surface maybe less than 10% of all breathing. so dont assume that they dont have gills. a friend of mine had a big bacteria outbreak in a 200+gallon tank wiped out his entire stock he now has two male bettas and 4 female bettas living in a heavily lanted aquarium keeps an eye on the condition of all fish and all are thriving.

I keep both of my bettas in the same type of tank-

I buy bottled water (the gallon sizes, filtered) and I don't heat the tank.
The water stays at room temp, which is warm as I'm in Texas and I don't keep the air on all the time (too costly :])

I hope that it's a good tank for them.
I just bought my newest betta yesterday and he seems a bit sad and wasn't eating much but he's been seeming better.

ihearslb - Hi there. The thing about having a heater is that, unless you live somewhere where the air never cools, a heater is essential for at least keeping the temp. in the tank consistent. I live somewhere very warm most of the time as well, but I have a heater in my guy's tank. Of course the heater doesn't even come on most days, but sometimes at night, I notice it come on when the temp. outside drops a little. This is important because fish are very sensitive to temperature change. It affects their immune system quite negatively if it happens too often.

People often want to compare "pet store" bettas to those found in the wild. There are no long finned bettas found in the wild. Of course they are related, but long finned bettas are pretty much a man-made fish, if you know what I mean. So, you could say that long finned Bettas natural habitat is the Tank. They have been bred for so long in tank conditions that they have adapted somewhat to that. And breeders keep their Bettas in temperature consistent tanks. However, even in the wild, Bettas live in Thailand, where the temperature stays consistently warm.

So, yes. That's why heaters are important for Bettas. :)

As a side note. You don't really need to buy bottled water for your betta. You can use tap water treated with a high quality water conditioner. (Prime is a good brand). The minerals found in tap water are good for bettas, and they can adapt to most Ph levels just fine. Again, with Bettas though, consistency is the most important thing. ^_^

Technically, bowls and cups are holding tanks until sold. You are suppoesed to come into a store knowing what you want and need. For a betta home must be cycled first by 5 complete weeks or suffer new tank syndrom. Bacteria must grow in the filtration unit and the walls of a tank must be pre-conditioned by the bacteria flowing in and out of a filtration unit. You must check for ammonia with tester purchased at your pet store until the ammonia level reaches 0.0ppm.
Now your ready for a betta. I recommend a tank of 3-5 gallons. Why you may ask. The reason is this. Small tanks tend to adjust to the exterior temp more easily cooling the bettas water, not good, immune system suffers in bettas, now they will die. PH leven must be between 7.0-6.6, water temp 78-80
Females can endure more water flow then males, males become stressed out if water flow disrupts thier ability to swim.
Also, a tank larger then 5 gallons could be fatal if your betta cannot swim fast to the waters surface and its depth, for they need atmosphric oxygen from the surface, struggling to get to the surface will sometimes suffocate the betta.

I can't really argue tank size but the one that I got is 4 gallons. I changed out the stock filter due to excessive turbulence and now have a simple foam / bubble filter.

My current little baby lives in a 20 gallon long. You do not need filters unless your tank is cycled and should do regular water changes with a gravel siphon. Also the absolute best filter is a sponge filter.

But the minimum for a betta to be ok is 2.5 gallons another smaller is torture. I still don’t understand how people can think its ok for any creature to live in such a small environment. I wish I could get my boy a 100+ tank but college only allows 20 gallons :(
