Grade "A" Onyx?

No current videos of running setup. This is what it looked like with no fish.

To me the only way you can grade an onyx clown is wether it's got perfect bars of if it's a mis-bar...

All the other grading is completely subjective, especially considering you just attempting to grade the different variants of a mis-bar in the first place.

I would also add the amount of black the fish has. For example, some people feel that -- and I tend to agree -- that for a percula to be called an Onyx, it should have a black dorsal fin. I also think some can be labeled "extreme onyx" when they have more black than a standard Onyx, meaning the tail or face has a lot of black.

Both Picasso, many will fill in with a lot of black as adults.
Onyx Picassos are Onyx clowns (Especially from the C-Quest lineage) with some extra markings. Like this beauty from Alpha.
