tiger barb died others dont seem right

Hello everyone somethings going weird here. had a tiger barb die yesterday no signs or symptoms of anything at all just dead next day. I always do my tests since i had a nitrite issue a month or two ago. Tiger barb had excellent color and was lively the day before. Now my blue barbs seem a bit out of it (not right) and hiding more than usual. I do regular water changes with prime all the time here are my test results. any ideas
Ammonia 0ppm
nitrite 0ppm
ph high is 8.2 cant get any lower iv tried
nitrates are at around 30ppm is my take but test is red for both 20 and 40 so.

Your pH is high. When you do water changes, try to mix the water you are presently using in equal parts with distilled water. That should lower it and, unless you have some rockwork or substrate that is keeping the pH high, your new lower pH should be pretty stable.

Nitrates are okay. If you are worried, you can try a nitrate-removing resin or media; they are fairly inexpensive. A lot of us have tap water that measures 20ppm in nitrates right out of the pipe!

How large is the tank and how many barbs do you have? I wouldn't keep Tiger Barbs in a tank shorter than 48" which means a 40-long or 55, and I would keep upward of a dozen. Aggression can't be sufficiently dispersed among only a few fish. . .Is it possible that this is the result of aggression?

I would also house only a single barb species to a tank. If by "blue barbs" you are referring to color variants of the Tiger barb, that combination would be okay.

thousands have lived without love; not one without water.

We need more data to suggest possible causes of the fish dying.

Tank size; fish in it (species and numbers); live plants?

How long has the tank been set up? When were the fish added?

What is the temperature? How often are water changes done, and how much water is chaged?

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
