I have never heard of them until now, looked them up and ..... ehh. I'm a huge clownfish fan, originals and designers and these ones just... idk... they look like they were bred with bettas. I'd have to see one in person to really get a good opinion, but from the pics I don't love them lol
I just looked them up too. They looked like photo shopped clowns to me. I saw a video of a longfin black Darwin clown and he looks like he's having trouble swimming. I'll pass.
One thing to consider with these clown fish is that they are poor swimmers. The fins inhibit their ability to swim as well as other clown fish. This can pose problems in regards to feeding and their survival in our tanks. In the wild, these clowns would typically die.
