H2o changes are basic maintenance for any fish keeper. No filter tin process all of the waste that accumulates. And you'll always need to add new water to replace that which evaporates over time. Bettas love it when you freshen upward their tank but but how often do you change a betta's water, anyway?

What H2o Conditions Do Bettas Prefer?

Bettas are so incredibly popular considering they tin can thrive in a wide range of water conditions. In the wilds of Thailand, they are found in shallow streams, rice paddies, ponds, and other slow moving, fifty-fifty brackish bodies of water. In these steamy atmospheric condition, the dissolved oxygen content gets so low that other fish often can't survive.

Fortunately, bettas have their labyrinth organ, which allows them to exhale air. See how your betta goes to the surface every few minutes to take a breath? It's literally breathing air, but similar us, because air holds effectually 100 times as much oxygen by book equally water does.

As well preferring very warm conditions, bettas also prefer a soft, acidic chemistry. The weed-choked environment of their home is total of decaying plant matter. Found tannins, humic acids, and other substances act equally acrid buffers, bringing the pH below vii.0. That said, bettas volition thrive even in alkaline atmospheric condition; but if yous can, keeping the pH below neutral will make them happier!

Full general hardness (GH) and carbonate hardness (KH) are too quite low. There are few dissolved minerals within the water, which is why their water is as soft as it is.

If you tin, it's a expert idea to go along aquatic plants alongside your betta every bit well. Plants take in carbon dioxide (CO2) exhaled by your fish as a nutrient and release oxygen for them, improving the aeration of your tank. Plants also directly consume all three nitrogenous waste products (ammonia, nitrite, nitrate) and utilize it as food, making them beautiful piddling biological filtration systems.

And if your male betta is happy enough, he will likely try building a bubble nest. Plants that are growing about the surface are what he tends to wait for considering they act as anchors for his bubble nest raft. In one case it'south secure and not at run a risk of floating abroad, he volition likely start looking for a female betta to entice to his love nest.

Why are H2o Changes Important?

Water changes are important considering it's the simply way to remove certain waste products in your tank. And while some other chemicals will break down over time, they accumulate much faster than the breakdown processes occur, making water changes essential.

Water changes are like a spring cleaning for your aquarium. You open up the windows, beat the rugs, dust the furniture…Together, the unabridged atmosphere of your dwelling changes and y'all experience much better as a upshot. Your fish will grow lethargic as chemicals accrue, making water changes are essential for proper health!

What Chemicals cause Bettas Issues?

The three major pollutants that should be part of any fish keeper'due south vocabulary are ammonia, nitrite, and nitrate. Together, these chemicals form the backbone of the nitrogen cycle. In my article on biological filtration, I go into great detail on how this process works.

But to briefly explain, your aquarium, especially your filter, is home to beneficial bacteria that swallow ammonia, the first and about toxic class of waste matter that fish and other organisms release. This ammonia gets digested and released every bit nitrite, which is less toxic but still a problem for well-nigh animals. Fortunately, a 2d set of bacteria swallow that, converting it into nitrate.

Nitrate tends to then accrue in your tank since the bacteria that eat nitrate need specialized conditions that are rare in most aquariums. Plants will besides consume nitrate (too as nitrite and ammonia) only unless you have a heavily planted Walstad tank, y'all can't rely on them for all of your filtration needs. Therefore, nosotros need to exercise h2o changes to remove this excess nitrate.

How Often to Change a Betta's H2o

At that place are a few factors that influence how oftentimes you should alter your betta'due south water. But the short version is that modest water changes of ten-20% one time every 7-10 days are best for your betta's wellness. This is also assuming you are running a filter. You tin also do water changes of xx-30% once every 2-iii weeks, but smaller water changes are better for stable water conditions!

How Oftentimes Do You Feed Your Betta?

How much nutrient you requite your betta is of import – and non just considering your betta needs to eat! Any leftover nutrient will contribute directly to increases in ammonia and other waste products. So when fish guides say "never overfeed," they hateful 2 things: don't allow any leftover nutrient to accumulate without existence eaten and don't feed your betta also often!

Some aquarists believe that providing "extra food" is a expert idea for their betta in case it gets hungry later. Any extra food is going to immediately start decomposable and create problems for your fish. It's better to underfeed than overfeed, in this case.

Bettas eat quite a bit in a unmarried meal; 1 solid feeding per twenty-four hours is all that they crave. They aren't virtually as active as tetras and other fast-moving fish and don't demand loads of food. Feed your betta enough that it's tum rounds out visibly and information technology slows down. The more than y'all feed your fish, the easier it will be to know exactly how much your betta will consume at every sitting.

If you enjoy interacting with your fish more often through food, you lot can also break upwards their meal into three smaller feedings per twenty-four hour period. Like all fish, bettas are continually willing to eat since in nature, they never know when their next meal is going to come up.

What Kind of Filter Practice Yous Employ?

If yous purchased your betta with a Spider Vine or other found growing out of its basin, you may take been told that the vine "filters the h2o while the betta eats the vine," in a sort of Circumvolve of Life story. Sadly, this is entirely untrue.

The plant certainly does uptake ammonia and other waste products but not nearly enough to entirely purify a betta basin. And bettas are 100% carnivorous; whatever root bitter is due to the betta finding some small organisms to swallow. Or it is exploring its environment with the simply grasping tool it has: it'southward rima oris.

Whether you adopt a sponge, power, or canister filter, you should always employ some kind of filter on your betta tank. Bettas have a reputation for not needing a filter because they are capable of surviving in small-scale, brackish bodies of h2o in nature.

But the fundamental word here is survive. Nosotros don't want our pets to simply survive in our care; we want to see our fish thriving, healthy and happy! So instead of providing the bare minimum, we can use a filter to procedure waste within the tank and lengthen the amount of time required betwixt h2o changes!

For the majority of aquariums, a high quality sponge filter provides plenty of filtration for a single adult betta plus some tank mates. Sponge filters provide non only loads of mechanical filtration capacity simply likewise offer a home to beneficial bacteria that feed on ammonia, nitrite, and nitrate (biological filtration). Many sponge filters even accept compartments for activated carbon (chemic filtration), completing the trifecta of ideal aquarium filtration!

Some betta tanks use undergravel filters only I'm not a huge fan of these. They trap waste under the gravel, where information technology tends to be slow to decay aerobically. And in order to make clean it out, you must lift the plates, potentially filling the water column with dirt and disrupting your entire aquascape.

How Big is Your Betta Aquarium?

Contrary to popular belief, large aquariums are actually easier to maintain than smaller ones for one very good reason. The more than water you have, the longer it takes for the chemistry to shift. Larger tanks go on within a stable temperature range, salinity, pH, and other parameters easily, which all fish prefer.

Still, yous're likely keeping your betta in a 3-five gallon tank, which is still fine. It merely means that yous have less of an assart for overfeeding and other potential pollution problems.

Irresolute Your Betta's Water

While yous can't utilise untreated tap water, testing and treating it doesn't have much fourth dimension at all! A petty modifying of the h2o's chemical science volition go a long fashion towards ensuring your betta remains healthy!

Supplies Y'all'll Need

Siphon Hose: a siphon hose is used to remove water from an aquarium into a bucket. Typically gravity powered, they can create a powerful amount of current that a long-finned male betta may non be able to resist. Then go on an eye on the tank at all times when doing a h2o change!
Dechlorinator: untreated tap h2o typically has chlorine or chloramine in it. These chemicals are used every bit disinfectants to ensure bacteria aren't transmitted into your drinking water. But these chemicals are toxic to fish and need to exist neutralized before adding the water to your tank.
H2o Test Kit: in order to monitor the conditions in your betta tank as well equally the incoming tap water chemistry, y'all'll need test kits for pH, GH, KH, and other parameters. Fortunately, yous can get the majority of the tests you need in a single Freshwater Master Test Kit.
pH Adjusting Reagents: if your tap h2o chemistry is very different from the range yous want to maintain in your betta tank, you lot'll need chemicals to raise or lower to pH in order to go on in an ideal range. Bettas are hardy upwards to pH 8.0 but vastly prefer 6.0-7.0. They are much more probable to show improve colors and breeding activity in soft, acidic weather condition.
Saucepan or No Spill Siphon Hose
Thermometer: when adding fresh water to the tank, a thermometer should exist used to match the temperature equally closely as possible. Temperature shocks can make fish sick just as with humans.

When matching the temperature of your incoming fresh water to your betta'south aquarium, know that yous don't demand to exist super precise. You can add enough water to bring the temperature downward two-3 degrees from the usual temperature or raise it past 5 degrees with no issues. Shifts in heat are much improve tolerated than common cold for tropical fish. But I wouldn't stress the fish by causing desperate shifts too far beyond these boundaries.

In case you aren't already, yous should definitely have a heater for your betta besides. One time again, the toughness of bettas can brand their lives more than difficult than they need to be. While they can live in unheated water, they are Southeast Asian natives that adopt temperatures around 78-84℉ or even warmer.

Unheated room temperature water is around 65-72℉ and needlessly stressful for the poor fish. A unproblematic plug-in heater sized for a small tank volition heave their appetites and disease resistance in no time!

Water Change Frequency

For aquariums of all sizes, information technology'due south much improve to practice frequent small (10-20%) water changes rather than infrequent large ones. Or rather, practice both, but don't rely on large (xxx%+ changes) infrequently.

The issue with large h2o changes is that they are a significant disruption to the established h2o chemistry. Bettas are extremely hardy and not probable to show too much stress. But it certainly won't be thrilled with, say, a sudden pH shift of half dozen.v to seven.5 later on adding tons of fresh tap h2o. Other fish tin be killed outright by such a change.

Determination

Water changes are of import and very easy to practice, then long as yous follow a few essential steps kickoff! Small, frequent water changes are always better than large, infrequent ones. When using a siphon hose, remember to scout out for your slow-swimming betta. And when adding fresh water, you'll need to practice your all-time to match the temperature and chemistry parameters because too quick of a shift can open up your fish to diseases and other issues.
