Hi,
The advise given in your other thread holds true for this thread.
Your tank is probably not cycled.
What test kit are you using? Most here recommend API Master test kit, it's very reliable, where the strips are not.
What are your readings for ammonia, nitrites and nitrates?
This will help everyone here help determine if your fish are ill or suffering the effects of an uncycled tank.
If your readings are NOT 0 ammonia, 0 nitrites, 5-10 nitrates, you should be doing daily water changes.
You really shouldn't mess with your ph, otherwise it will always be fluctuating. Your fish should be able to adapt to your ph.
Your fish don't need a snack, feed them once or twice daily and only the amount they will eat in a few minutes.
Good luck.
