High pH ?
--High PH is not a requirement at all (even for red cherries) as long as you avoid extremes to the downside. Just treat them like they are Red Cherries and they'll be fine.
It is very hard to make generalizations about shrimp. The same is true of fish. South American dwarf cichlids need soft, acidic water. Rift Lake cichlids need hard, basic, alkaline water. The same is true for shrimp. Some shrimp prefer basic water. Some prefer acidic. Some like cooler temps. Some like warmer temps. It varies from species to species. For most species (assuming you can identify the species), the preferences are not well documented. However, most shrimp seem to do well under nuetral conditions.
