The pH is way too high. Keep it near 7.

Adding some driftwood to the tank will lower the pH gradually and naturally. You don't want to use chemicals.

Nitrates could be lowered some more with water changes. Your fish must ve dying from a disease inside tank. how are they reacting before dying. Any signs of illness?

Just to make sure. When your cleaning your tank you dont use any soaps or chemicals?

And also what water conditioner are you using. Make sure its not out of date. Sometimes they are in affective if not stored properly before been sold.

Also have your fish started dying after adding new fish to your tank? If so its most likely some sort of parasite

I would have to agree with this or as your ph and nitrates are a bit high it could be the water that is killing them slowly and that wouldn't have any symptoms. What are the fish you are loosing? And what I would do if find out what their ideal conditions are and if they are all different from what yours are running out then the likely course is the water but if you have just added fish to the tank then it could be a parasite, even if you have new plants it could of been transported on that.

Hi lizmunn

There are a few issues that spring to mind here that may need addressing. The ph is not one of them if it remains stable. Fish should be able to adapt to this ph but they require a careful acclimatisation process.

How long has the tank been running is the first question I would ask.

I would recommend you buy your own liquid test kit as often LFS don't do the necessary tests, do the tests wrong or use unreliable testers such as test strips.

You need to see for yourself what the results are then we can illuminate a water problem.

The next thing I would look at is your stocking levels. I think personally there are to many fish in your tank now. I don't know how many you had before you lost some but I would look at reducing the bioload (waste production) of the tank.

There may also be some compatibility issues with your stock. Danios and tetras like to be in groups of at least 6 for example. I don't think fighting fish and gouramis get on very well and depending in the type gouramis they may be having issues between themselves.

What is your maintenance routine?

I bought fighting fish from a specialist place that were altogether originally

No biting chasing etc

My routine is weekly water change and filter clean with gravel clean

Tank has been set up for over 5 months now only recently started to have problems
