Advice on adding second clownfish

[TAO78]

Hello! In my previous post, I was seeking advice on what fish to add to my 24 gallon cube next, I have decided to add a second clownfish! I started with a pair, unfortunately the one was killed by the other. He is about 1.5-2in. How do I go about adding in a second while minimizing the risk of them killing each other? Thank you!

Get one that’s smaller and it will be the male.. yours is big enough to be female now.
