Good Morning my friend. I would love another Copperband and this is one of the few times my tank doesn't have one. But with 50 fish, I really shouldn't add anything, especially a fish the size of a copperband. I have a lot of algae now and that is partially due to having to many fish and my water source in the sea is loaded with fertilizer from the farms and golf courses I am surrounded by.
The Hippo tang I always had and that small Tamini tang, just one day happened.
Also, fish never die so I can't replace them.
