Bettas Without Filters

[Maddycat]

Hi,
 
I was wondering if there was any members out there that don't have filters in their betta's tank. I am trying to give it a go first and see if it works without to much daily water changes.
 
Any tips or success stories?

No fish should really be without a heater although i do keep guppies in a 20 gall container with plenty of live plants and bettas must have oxygen so you would at least need a sponge filter. but you want my advice dont do it get a heater and a filter and an appropiate tank size of 2.5 gallons and up.  whats your tank size now

Hi,
He has a heater already in his 2.4 litre tank . We have only had him for 4 days. We have bought him a 15 litre tank all to himself. He has a bubbler but I was hoping we would be able to keep him without a filter.

It is possible to have a Betta without a filter but you would need to do daily water changes of at least 50%, if not more. 
Its far easier in the long run to have a filter IMO.

Bettas don't really need oxygen in the water because they breath mostly from the air, so, in theory, as long as the Betta has access to the surface, they could live without any oxygen in the water. But, I would not personally try this.

Bottom line is you can keep him without a filter however if you want him to be healthy and live to his full life expectancy, then he needs a filter.

Didn't the labyrinth organ evolve for those times in the year when the fish only had pools of stagnate water to survive in till the rains came? If that's true than they wouldn't be able to solely survive without oxygen in the water indefinitely.

just dont do it bottom line

It's because the rice paddies are really slow moving so don't have high oxygen content (thats how I understand it anyway, you may be right though), same as a Gouramis habitat I think.
I'm not sure if they could always live in no oxygen waters but considering that any amount of surface agitation will put oxygen into the water, it would be next to impossible to have oxygen free water.

They don't live in small puddles for the entire year - it's all seasonal with the rains...

2.4 litres imo is way too small, it's barely big enough for him to turn round & with that small amount of water you'd need to do almost 100% daily water changes to keep ammonia at bay without a filter.
He'll be much happier & healthier in the bigger tank with a filter

A Betta should be living in a 22litre+ tank with a filter, and a heater. I'd advise you to get a bigger tank than 2.4 litres, and get a filter

So basically, filter would be a lot "betta".

In south east asia like my country, like 80% betta are kept for fighting purpose, they keep in coffee container without filtration and it is fine.

Yes they may survive but I doubt they live a very long life nor have any quality of life. Surviving is NOT thriving. The aim of a decent fish keeper is to provide the best possible care, not 'oh that'll do' - that opinion of fish keeping won't get anyone very far on this forum I'm afraid.

Bettas live in rice paddies and slow moving streams in the tropics where the temperatures are really high which depletes the water of O2.  So the high temperature and the slow to stagnant water led to the labyrinth organ not them staying in puddles.
 
 
Bettas are perfectly fine to be kept in tanks with no filter(they are one of the very few fish that can live very comfortably like this).  This is contradictory to what a lot of people think when keeping fish.  It is more practical and better for the fish's health to use a filter to keep a cycle in the tank which cuts down on the frequency and size of water changes.  Like I posted on your other thread, a 15L (3 gallon) tank is perfectly fine to have without a filter.  You will need to do 100% water changes every other day and your betta will be perfectly fine and thrive as long as you have the heater at a correct temperature, feed him a good quality food, and otherwise care for him in a excellent matter.

If we want the fish to thrive, then don't keep them in aquarium, don't feed them dry food pallet. They tend to be swimming freely in their natural habitat. A tank is not their natural habitat. Some species of animals can withstand direct sunlight, some are don't. Same with fish with their environment

I've been keeping betta since childhood. My uncle breed them. Filtration is not their big problem. One of the easiest fish to keep as long keep in solitary tank. Here, People use betta for fight and they're always keep in ketapang leaves solution for their suplemen. It's ok for them, yet they're survive and healthy.
