Clown fish

[Nakie31]

Hello all I have a clown fish in my 45 gal. I got him from petco so I quarantined him for 30 days he showed no signs of illness and was swimming just fine. So into the DT he went along with my cleaner shrimp that I’ve had in my 200 gl. tank for about 2 years. Recently I added 2 purple fire fish everything in the tank was doing fine and eating well, but the clown fish is now acting like he doesn’t was these new fish in the tank he just keeps swimming up and down the glass. He doesn’t look sick or anything so I think he just need a partner so should I get another clown to pair up him?
