AWESOME fish!!! Coloring seems to stay whether stressed or not but at first is brighter...we get them in, and they're AWESOME!!! One of my favorites! Thanks for posting!

Tres cool and very cute!

Yeah the last one I saw kept its colouring all the time!

Thanks guys good to know they keep their colour. I am beginning to think the opposite is true for these guys. I've noticed that my dumb mimic tang doesn't really like him (no idea why since he's a fairly peaceful tang and obviously nothing like a blenny) and will sometimes chase the blenny back into hiding in the rocks. When this happens I've noticed that the blenny will get darker in appearance.

Some tangs really seem to hate gobies and blennies for some stange reason.... The chevron in the display at the shop hates the orange spot sandsifter that is in with him and my chevron at home hates my shrimp gobies with a passion and chases him them into their hole every chance he gets

It is probably setting boundries and letting the blenny know who is boss.

Your fish Is a new addition, it should settle. My yellow does it to every fish I add for about a week and then it's over.

Good luck.

WOW
 

He looks wicked!!!
