Pets in Blackrock Depths

[Finduilas]

I tried the search function, but it didn't bring anything relevant up, if it's the wrong place, feel free to move the topic.
I'm currently running Blackrock Depths with an alt hunter for transmog set. Especially the ring of law. While doing it, you get random creatures to kill before you get the boss (spiders, bats, worms and beetles so far for me). Out of interest I beast lored the first beetle I got. They are tameable. I saw white and black beetle skins there, both not listed on our Petopia side as tameable in Blackrock Depths. I forgot to take a screenshot and only got other creatures after the beetles, but I'll edit it in. The spiders and bats are listed as tameable on Petopia, the beetles and worms not.
The worms come in three different colors and are exotic. I added a pic of them.
For those people who want a white beetle and don't want to get into a raid, the Blackrock ones are a nice alternative, you just have to get lucky to get them in the ring of law.
Also added a pic of the map, where you get them.

edit: I edited the title, so it won't be misleading

I think they are these ones http://wow-petopia.com/look/silithidsca ... white.html

Ah this might be. I didn't tame them, so I don't know if they are color changers. Thank you Nefretiti. Maybe someone can confirm it?

[Neilaren]

They are. I own one! (The beetle, I mean. The worms might be, too)

Of course, if you want them to remain color-changers, you should tame them before Mists.

I've tamed them in beta, and they are color-stable.

Thanks everyone for your help! I edited the title, so it won't be misleading anyone. So we know if you want your white beetle to be no color changer, you still have to got to AQ or wait for Mop.

The worm has only 2 colors, pink/white and dark grey/grey, that it changes into.
