While I'd prefer something a little less aggressive, like a couple of Pajama Cardinals, a couple of Percula Clowns would be fine. They are hearty and don't get too aggressive toward new fish. Other clowns are just too aggressive to be the first fish in the tank. Once you have added the Clowns, don't add more fish though until you verify that ammonia stays down for a couple of weeks. Feed them frozen Brine Shrimp. Just a few shrimp each per day for the first few days, then ramp up feeding slowly.I wanted to do a clown pair first. Safe to do so? Almost 5 weeks. I said I'd be patient but I'm getting antsy lol
