Personally from my experience, the designer clowns tend to look great as their young, but as they mature their bodies become more and more misshapen and deformed. I saw a big thunder maroon clown at nearly 4” and it was sad how messed up the poor thing looked.
Meanwhile I have a wild caught female maroon who’s nearly 4” also and is beautiful. A work of nature (literally).
I am not against captive bred clowns at all. And I have no doubt that captive bred clowns can’t live the full 25+ years. Normal colored ones probably can and will, same with some basic/natural morphs like the black and white, snowflake, and maybe even the lighting. However when you start to get into the crazier morphs like the “peacemaker” maroon clownfish out there that’s when things start getting crazy....
