Adding a new Clownfish to an established tank

[KeystoneMalone]

So, long story short, my nuvo 20 has been up and running since last november, I had 2 clownfish that I bought as juveniles and introduced to the tank at the same time and were doing great. Came home from work the other morning and noticed one went missing and to my dismay I found him dead on the floor. I have a lid on the tank, but there are small gaps around where it meets the tank and he jumped. I cut some acrylic and glued it to the lid to eliminate the gap, so that eliminates that issue.

I know clowns can be territorial, is it worth trying to add another? or would it stress out either fish too much?

Would I be better off with a different species, like a purple firefish or goby to avoid possible aggression?

Any advice would be super helpful-

Thanks,

It will be fine. I've done this a few times. Get a clown of the same family and half the size of the current clown in the tank. There may be some fighting at first but the small guy will submit to the larger one. I just did this with my super aggressive saddleback. A few days later he is sleeping in the BTA, which is huge for her

I also did it with this pair

Yeah, just add a smaller one of the same species. Should be fine.

What if the clown I currently have is really small? Is it okay to add new larger clown?
