However, if you do NOT have any tap water dechlorinator, then let the water sit for 48 hours (or at least 24 hours) to get rid of the chlorine and other harmful chemicals in the tap water.
well i just got my betta and am already an "expert" lolsz well the store i bought my betta from petco and they gave me a care sheet in this care sheet it tells you do a complete water change for small bowls (less than 2 gallons)once or twice weekly (but i recomend u do it every 3 days for a less than 2 gallon bowl or w.e);in larger aquariums change 10-25% of the total volume of the water every two to four weeks, or more often as needed even dough i got a 2 gallon and i change it every five days
I do it right away. Once a month I clean his tank fully, all gravel, plants, decorations come out. I scoop Craig up with a plastic cup-then using hot water clean everything, change the filter, rearrange the tank, add water about 1/2 filled with clean, conditioned water, add Craig and then put filter in and fill up tank. Of course, the water has been getting ready for 24 hours.
Every week I take out about 1/2 and replace it with above but, do not change filter.
Hope it helps.
Its ok as long as you let the water cool to room temperature before adding the water back to the bowl, or adding the betta to the water. Also, it is completely unnesseary to boil before putting in your betta's bowl.
If you are using tap water for the bowl without conditioner parts of the betta will start to "shed". If you aren't using conditioner then I recommend to go to a pet store and get "betta fish conditioner" that protects against tap water.
no as long as there is water conditioner/ purifier in it
If your betta is in a tank or bowl that is 2.5 gallons or smaller, you should change 100% of the water once a week. If it's a 5 to 10 gallon, then change 50% to 75% of the water each week. Make sure that the new water you add back in is the same temperature of the old water, and use a water conditioner.Your betta only needs to be fed 2 to 3 betta pellets at a time two times per day.
Typically a betta will increase in colour, and in some cases change colours somewhat as they age. If your betta begins to lose it's colour, check for water quality problems or an illness.
To the best of my knowledge no one keep those kind of records. Bettas are mature at 12 months, past their prime at 2 years old and ancient fish at 4 if they live that long. I have a Betta fish that is now over 5 years old because I change the water once a week with 2 gallons of purified water and I add about 20 drops of Splendid Betta Complete Water Conditioner to it. Using the water conditioner is a MUST to ensure that your Betta fish will live a very long life. I also feed my Betta fish 4 pellets of Hikari Betta Bio Gold once a day in the morning and 1 pellet at around 7pm.
every two weeks then change the water every four
I'm assuming you have access to a fresh water crab because a Betta will not be able to live in salt water. The crab will attempt to catch and eat the slow moving Betta. It is only a matter of time before the Betta is killed.
2 times a week
Tap water is the best water for betta fish! There is no need to go out and buy expensive betta fish water...it's no different then tap! If you want to be sure that the tap water is safe for your betta, put in some sort of conditioner for the water.
Betta splendens do not get angry with people. If you think your Betta is angry with you it will be your guilty concience. I advise you to look after your fish well. Give it good food, good conditions and change its water regularly and thereby have no conscience pangs.
You should change at least 50% of the water in your tank each week at minimum. If your tank is too small, to over-stocked, or you do not have enough filtration, then you will need to change the water more frequently.
