I have two paired clowns and 1 fire/blood shrimp in a 26 AIO. The fire shrimp took over the spot that the two clowns had claimed prior to shrimps arrival. The fish roamed freely the first couple of days after shrimp was added. Now they just hide in behind a rock & rarely come out. Should I get rid of the shrimp? He is larger than the fish. I also added two corals the same day. I just want my fish to swim happily & freely again. Temp 79, Sal = 1.025, Ammonia = 0, Nitrate = 5, phos = .20, PH = 8.0, dkh = 9, calcium = 390
