do you know how to sex these christian? nice fish!

Is he pure cobalt? He has the bars and black on pelvic fins. Don't think I have seen one like that before.

i was actually thinking that bip i didnt think cobalts had stripes..i am most prob wrong..

Might be a male Minos Reef red zebra (i.e., 'wild type'), based on the characteristics bip pointed out AND the presence of 'egg spots' on the dorsal fin on this specimen (which m. callainos lack but m. estherae have).

guyz i have no clue.....i recently got these from a friend doing a trade and he told me these were cobalt blues....they are huge...around 6 1/2 inches and very fat lol...this guy shows his bars sometimes but is usually all blue..the other one i posted usually always shows the black bars...

Kay Bee i think you might be right on what this guy might be...did some research and it does seem to be a m. estherae blue male
