The "black clown" your referring to is called a midnight clown. Do a search for ORA clowns your see them all! Here's a link to the midnights (if it works)
Look around their site you will find a spot to email about what LFS
in your area order from ora! Not sure where your from but here in the east the are the big (not the only) supplier for this area, they are based out of FL. They may have other locations too, not sure. The only problem my LFS
told me about ora designer clowns (the rare ones anyways) are very small when they come in.
The "white clown" Is called the platinum clown, one of my favorites! A paid is On my "fish list" for some day! My LFS
has a pair or ora platinums he said he'd sell them for $400 for the pair. For not they look pretty in his tank! Lol
Here's the platinum link..
Good luck!!! Let us know what you get!!!!
