I have a 20G that has been set up for three and a half years. It's got a mix of softies, rock flower anemones, a small tuxedo urchin, some snails, and at present, one (probably now female) ocellaris clownfish. The clown was part of a pair that I had for three years. They were purchased as juveniles, paired up easily, and were together until the female unexpectedly died back in October. She showed no symptoms, wasn't acting weird or anything, and I just found her dead one day. The male has been totally fine health-wise since.
I tried adding a new, very small, ocellaris around Thanksgiving. My thought had been that since there was such a size difference that the older one would have become the female by now and the younger one would accept being the male. This didn't turn out to be the case, as the new clown was killed by the old one within a day or two of moving it in to the main tank (I had it in quarantine for two weeks with no signs of any health problems before that). The old clown just terrorized it, even though I had it in a separate breeder net within the main tank, and the old clown couldn't directly touch it.
I would really like to add another fish (or maybe two if they were smaller) to the tank, but I'm concerned about adding another clown for fear the old one will go crazy on it again. Any suggestions for possible tankmates for my crankypants clownfish? I'm open to anything that would be happy in 20 gallons and won't destroy the coral, including suggestions on how to try to possibly add another clown again.
