Redtail shark in high PH?

Does anyone think it would be ok to keep a redtail shark in a ph of 8?

Red-tails have a much wider tolerance range to pH levels than most other fish. Anywhere from 6.5-7.5 will suffice. Acceptable water temperatures are 72-79 °F. They can reach 5 inches. They don't tend to grow as long in smaller aquariums. Females are typically a little smaller than males. Their life expectancy is up to six years.

lol just incase you didn't know the rest.......... SOOOO 8 might be ok, if 7.5 is, you know....
