Bangaii Cardinals in Reef w/ Shrimp


I have a 75g reef and was thinking about getting a pair of Bangaii Cardinals. I've read that Bangaii Cardinals should be monitored with shrimp. Does this pertain to all species? Here is what is currently in the tank.
2 true percs (mated pair)
3 green chromis
1 royal Gramma
1 firefish
1 sixline wrasse
1 coral beauty
1 pep shrimp
1 cleaner shrip
various snails and hermits.
Corals are mostly mushrooms and polyps.
Does anyone have experience with these cardinals and shrimp? Or any experience with this fish at all? All input is greatly appreciated.
