Yes just put them in a floating basket away from the females normal home. Give it about 3-5 days with keeping an eye on them and she should except him. I do this with pairs all the times usually with no issues. Kinda like a new place for both. They are however not same breed of clownfish. Blacker ice is ocellaris while picasso is percula. They will be a hybrid pair but usually no issue excepting each other.
