I have found that angels will spawn over a wide range of pH and hardness, but will only tend their fry at pH levels in the 6.0 to 6.5 range and hardness around 3 degrees GH and KH. Tetras, rasboras and lots of cats are also pH and hardness sensitive. As long as you've been on this list, I'm surprised this is news to you.
