If you decide t get a pepper mint shrimp, make sure that you have no other more dominant shrimp in there or else they will force the Pepermint o hide out and he wont do much. In that case it is nice to have the Joes juice. I have used it a few time and it is quite interesting how fast they get nuked. It wont hurt any thing else, just make sure you shut off alll your power heads and stop the pump. that just makes the stuf go all over the place.
