my blue tang eats nutibranch

[weileong]

This morning lights just on and one green colored nutibranch crawling on my tank wall. My blue tang swims near it and graps it and split out. I thought okie, then in another moment it graps and shallow it man.

And I thought they were poisonous??? The blue tang still alive after 3 hrs.

Better pray hard it doesn't die.

green ones are most likely algae eaters. Maybe the blue tang liked the 'concentrated algae biscuit'

the green ones comes with my green buttons as they are the same color. Just got a big shocked when I saw that as I always thought they know well enuff not to touch those. I had been removing many of them in the morning and was about to remove this one before the blue tang got it
