I recently bought two amano shrimp that only lasted two days in my tank. Luckily my lfs will replace newly bought fish that have died. They test your water first, and won’t replace them until the water is considered safe. When I brought my water in they said my ph was too high and that’s probably what killed the shrimp even though everyone else seem fine. I’ve been trying for days to lower the ph with ph down but it seems like it’s stuck at 7.8. I’ve only been adding one dose when it’s been more than 24 hours so it doesn’t stress the fish. Today I instead put in Tertra easy balance plus to see if that helps at all. I would try driftwood but I don’t have the room because I have so many plants. I haven’t been able to put fertilizer in the tank for a while and have been afraid to mix it with the other stuff, but could it maybe help? The ph used to be better so I was thinking maybe the lack of fertilizer raised it.
