水草情迷

In my tank pH is 5.5, base on the reason to display the colour of fish, so i cannot rise it.

i would like to know that i can add what type of shrimp can work in these pH valve. Because i need to add them to work inside my moss land. i have try to add many times, but all dead within one week. in pH6.5 i can keep them for a few months, but cannot keep in ph5.5

any suggestion for add which type of shrimp? many thanks.
