Why Dont Bettas Require A Filter?

[mike_nofx]

Why is it that bettas can survive in a filter-less tank (therefore being uncycled)??
Are bettas cold water fish?
and, why can you do a 100% water change and the better doesnt get sick??

The filter is more of a personal prefference, I think. Both my 30 gallon sorority tank and my 10 gallon tank for 1 male have filters, but both have a piece of plastic coming down in front of the water flow to help cut down on the current. I've found that without this the Current becomes too strong and stress's out my male, who will fight it trying to swim to the surface. In the wild, they live in water that has little to no Current.

Betta's are not coldwater fish, they are tropical fish and as such, need some sort of heat for their water. either a heater or being in a really warm room... The water tempshould at least be 70 degrees F, and prefferably more around 75 - 80

If done properly, the 100% water changes help, not harm, the betta. They do not have to live in cycled tanks, and from what I've read, most people -don't- cycle anything smaller than a 5-10 gallon tank so the 100 changes help because it gets rid of ALL their waste, thus, making the water clean and helping to prevent fin rot and other such things.

They don't need a cycled tank because you artificially do it. By doing water changes every couple of days and then 100% water changes, you remove all the ammonia/nitrite/nitrate when you change the water, so you don't need as much of the bacteria. Well... it made sense in my head

What makes you think coldwater fish dont require a filter!?

i made a DIY sponge filter for my betta today

so happy with it as i change ajust the current as much as i like etc.

it's only a 4 gallon but i wanted a filter to move the water abit and i know betta's don't like much current so i added to a plan for a DIY filter with my own few touches and left out some of the plans.

the plan for the DIY sponge filter is under as it happens DIY tanks of something on this forum just look at the pinned topics it's in there.

Any fish can (with the exception of the ones that die if you as much as look at them...). It's a matter of getting rid of the toxic chemicals before they become toxic enough to harm the fish. With cycled tanks, thats the bacterias job, with uncycled tanks, it's down to water changes.

Are bettas cold water fish?

The general reason a lot of betta tanks are unheated is that in modern centrally heated houses, room temperature is generally adequate to keep the water at normally accepted 'tropical' temperatures, or just below.

and, why can you do a 100% water change and the better doesnt get sick??

Very few fish would be harmed by 100% water changes, in fact, a lot of breeders do several 100% water changes a day on fry tanks.

i personally dont think its a case of they dont need them, just they can live without them..if you keep regular with the water changes then theyre fine. filters make yours and the fishies life easier (provided the current isnt too fast)

A betta can live in a tank without a filter as it has a labyrinth organ that allows the betta to breathe air from the surface rather than through his gills from the water like most fish.
