Pix & ID: Critters that come in your rocks: the good and the bad.
- Thread starter Sk8r
- Start date
So my tank has been cycling with live rock for about 4 days now and a few hitchhikers have started to show their face. Mainly just 2 small crabs that I spotted 2 days ago. This morning I woke up and found this little dude cruising around. I went through this thread and I'm pretty sure it's an Asterina Starfish.
Thoughts?

Good to know, thanks!

More pink stuff.

Sorry for the two separate posts, but I couldn't get the two images to appear in the one post. This is more of the stuff starting to appear on my live rock. The rock was out of water for six months, and then added to this new tank, with a couple of bits of live rock from the aquarium shop. The tank has been cycling for a week, now.

Need help with identifying some crabs i found on my live rock
Need help with identifying some crabs i found on my live rock
I heard a lock clicking/tapping/popping noise coming from my LR and upon investigation found some crabs. Could these be causing the noise? Or something else? I bought my LR from tampabaysaltwater.com and am BRAND new to saltwater. Any help would be greatly appreciated!!

Hairy crabs are usually bad and will eat corals.
The other is a porcelain crab. They are filter feeders and a good addition to any reef system. The clicking you hear is most likely a pistol shrimp (not bad, but noisy), and you may also have mantis shrimp (bad if u like having snails, hermits, etc)

I recently acquired about 140 lb.
of live rock from another reefer that had it in his tank for over 10 years. I've been "cooking" it for a little over 2 weeks now and while I was doing a water change yesterday I noticed some black slime and handful of large white bubbles. Any ideas on what they are?
Thanks!

Is there are rule of thumb for the number of bristle worms? I'm new to the marine world and got a used tank that came with rock that sat out of the water for some time. After setting up the tank and letting it run for a while, I noticed the worms. I added a piece of shrimp one day, and dozens and dozens of them quickly emerged and attacked it. I was pretty alarmed at the site and my first instinct was to get rid of them. I read more about their beneficial effects and decided to try to keep them. Now I wonder how many I should have. So far I'm going on the advice that if there isn't enough for them to eat they will naturally die off to a level the tank can sustain. Are there dangers in having too many? So far everything seems very happy.

Looks like sponges to me.
Mmm, let's add that if you have softies, they can be a problem...or at least that there is a species of asterina that is predatory. It would be hard for one of these to transit through a pump to the DT, but it could happen.
Mine occasionally leave a brighter pink track across my coralline. That's all. And there aren't many.

Can someone ID this critter that is floating around in my sump area with no flow?
It has multiple arms/tentacles (+20) that are stretch out an retract. I noticed that it has split into multiple smaller ones since I've taken these photos. I want to ID just incase they are harmful for my tank.

Harmless terebellid worm. Grab it and place it into your tank.
