Is this a tomato or cinnamon? I've been thinking of finding a mate for him/her but not sure which species it is. I've seen tomato's with and without the black sides. Any help would be appreciated.
Tough to say whether those are tomatos or cinnamons without seeing the pelvic/anal fins.
Excerpt from above link:
Amphiprion melanopus (western Pacific) is also similar, but generally has a broader white head bar and specimens from most areas (except eastern Melanesia) have black pelvic and anal fins.
