Could it be too young? See below. I got this in search if what misbarred means..
There are no pictures in your other post, so I couldn't make out what you were talking about...
A. ocellaris and A. Percula juvenile development
Multiple observations at C-Quest demonstrate that A. percula
are quite slow to develop the second and third white bands. A.
ocellaris develop all 3 white bands in about one month; however,
A. percula do not develop the second and third color band until
they are 6 months to a year old. For those who have access to
Gerald Allen’s and Daphne Fautin’s Field Guide to
Anemonefishes and Their Host Sea Anemones the photo shown
at the beginning of chapter 2 may not be misbarred wild A. percula
but simply young A. percula.
