ID Fish in my tank

Today i saw a fish hiding under a rock hes about 1-2 inches long. He hangs upside down on a rock white with black stripes and looks like on of his back fins have spikes on it.

Any idea? Salt water reef tank.

My blue tang disappeared 3 days ago when i added new corals but my tang was like 3.5 inches long so no way he could of eaten him (i hope).

 

Any pics?

Ive never heard of a fish being a hitchiker

 

My camera sucks, i have a picture but all u can see is like its size lol

 

You said its black and white, do you have a body shape description, a little more detail could help. Theres lots of black and white fish

 

i have heard of it once, on 3reef. it was a couple of weeks ago but someone said that they got a baby hippo tang w/ his LR.

porky what is the body shape of the fish? mabye a damesal?

 

A skinny more than wide, ill draw a picture with paint. BRB!

The spikes are on the start of his tail.

 

lol Im sorry but that could be the worst painting of a fish I have ever seen. Sorry... A+ for effort.
And I still dont have a clue what that could be, maybe somekind of blenny or goby

 

By the way, that pic should be your avatar or whatever all these people have pics of when they post

 

Once again, an A for effort but there will need to be more then that! Work on the camera skills in the meantime!

 

But the fish doesn't sound like a fish that can possible harm my corals + fish? Thanks!
