couple of questions re: blenny and wrasse

[airtime23]

1) Has anyone heard of or seen a bicolor blenny lose its bicolor? LOL. By that, I mean that my bicolor changed to just black a few months ago. He lost the yellowish orange tail. Now jet black all over. He's doing just fine, otherwise.

2) Has anyone heard of or seen a malaranus wrasse have an open mouth at all times? Mine has had his mouth wide open for at least 6 months. Doing fine, eating like a pig, no issues otherwise.

1) seen a lot of all black bicolors but that is at the wholesalers and didn't know they may have changed. I thought it was more down to regional variance as the bicolor shows a lot of this.

2) the mouth shouldn't be open so it's likely damaged it. This can happen in shipping or sometimes in tank when they dive head first into the sand. Mouth damage normally isn't good news so it's nice to hear yours is doing well.
