Well, I hope I didn't misrepresent, but the work I've been doing isn't viewed as a bad thing, not by me anyway. Yes, it's TBS rock, but I'm very happy with it - good and bad hitchhikers alike. I love the diversity I have, and I even think three mantis are awesome, even though they give me headaches too. The one I have in my Pred tank is so cool, he swims all around and patrols his area, lol. I wouldn't trade it. I could've done without the ciranolid isopods, but I haven't seen any of them in weeks.
Bristle worms are good cuc. I was sad I didn't get any on my rock, but my LFS has a tank that's overrun with them, so I got one off of them. I didn't foresee the blenny's going crazy on it and killing it though, so I'm going to get a couple more and put them directly into the rock where they can hide before the blenny's can get to them.
What do you mean it doesn't bode well if the rock has sponges?
