Sorry to hear about your loss, Jim
In a couple of different tanks at different times over the years, I lost mates to both ocellaris and skunk clowns. Each time, after waiting a week or so, I simply added the replacement clown to the tank. Each new clown was persistent in trying to get close to the original clown, but the original clown spent 2-3 days fending off the attentions of the new clown with aggressive behaviour. In the end, the original clowns accepted the new clowns, but I was always a little concerned about harm coming to the new clowns for those few days.
