What kind of fish that hides behind green and yellow seaweed?

It's impossible to say for sure what kind of fish hides behind green and yellow seaweed without more information! There are many fish that camouflage themselves in seaweed.

To help narrow it down, tell me:

* Where is this fish found? (Ocean, lake, river? What region of the world?)

* What size is the fish?

* Does it have any distinctive features? (Color patterns, shape, fins?)

Once you give me more details, I can help you identify the fish!
