What happened if you put your beta in a smaller bowl then added some rocks and the next day the water turned a dark bluepurple so you changed the water with bottled water and 2 hrs later the beta died?

Answer 1

The first question that I would ask you, how was the betta acting when the fish was in the dark bluepurple water, did it look like it was struggling to breathe before you put the betta into the bottle water, I have never used bottled water for keeping fish, I would suggest just using a empty gallon milk jug or half a gallon jug filling it with tap water, and keep it some where out of the way, and when you change your water use the milk jug water also keep the cap of the jug when storing, I would say something in the dark bluepurple water caused your fish to die, if the bottle water was at room temp, and not chilled or cold, a betta prefers warm water, they do not do well in cold or chilled water, 76 to 80 degrees is what this fish prefers. If these were new rocks that you have never tried before, there may be excess dye on the rocks that colored the water and killed the fish. If you have not already, test the rocks in another water vessel, or the tank seeing as its vacant. == == Filtered water is great for fish. It was not the water, but the rocks (as stated in the previous answer).

ALWAYS thoroughly rinse ANYTHING you put into an aqarium!

If you see the water turning a color, continue to rinse until clear.

This will remove some harmful dyes, chemicals, or sediment.

Better yet, do not put pebbles into your fish tank that contain dye.

No matter how miniscule the amount, it is not good for the fish! ______________________________________________________ As stated above, aslong as it was not chilled water, as long as it was not carbonated, and as long as it was not flavored, I doubt it was the water. I have to question the rocks, as I have set up hundreds of fish tanks, both big and small, and I have never seen rocks turn the water anything but cloudy in appearance. Most fish gravel is not dyed but is painted instead with a nontoxic paint, so if it loses its color (and they usually do after a while) it does not change the color of your water and most of the time you never see the mini sized paint chips that settle into the substrate. The gravel has to have had some sort of chemical on them for this resulting purple color and this unkown chemical agent is the fish killer I would assume.
