how high? pH won't kill fish if it's too high or too low unless it is fluctuating or just plain rediculously high (8+) or low (<5) .
"fixing" pH usually means dumping in a chemical- don't do that! If you're really worried about pH, do small water changes with RO water to bring it down. I'm talking like 10% of the tank's volume. There are other ways to naturally bring down pH.
Honestly, zebra danios are very hardy in high or low pH. I think it's more likely something else that is killing them.
