New Corals

I have new corals popping up on the rock were my animon is staying. Some people say some corals can be danger like weeds to other corals.
Can someone identify these new one and tell me if they are a danger to my aquarium.

Hmmm, I hope someone out here is a saltwater reef enthusiast because I don't have a clue. Welcome, we could sure use a saltwater person on here to help people like you, so stick around and feel free to inform us of what you know.

Welcome to our forum. A number of saltwater topics are listed under your posting, and one of our saltwater enthusiasts will probably be able to answer your specific question. In the interim, you may want to check Google.

Thank-you for the welcome, your site looks very informant.
I will wait and hope someone replies with required info

Again thanks.

Gee, seeing your aquarium I start thinking I should move to salt water...
Say, can't you ask the seller if his corals are dangerous or not to others?
If I'd buy fish, I would certainly expect the seller to warn me if they were predators...

I would ask, but the problem is that they popped up on their own from the live rocks. I have other that just appeared but I know what they are and no problem.
You never know what will pop up from salt water aquariums.

You can check out this little video 2 of my fish that clean rocks http://vids.myspace.com/index.cfm? fuseaction=vids.individual&VideoID=43875462

So you actually buying a live rock, and you're never sure what's inside?

BTW - Cool video

Yep, in salt water live rocks is your natural filter so no external filter is required apart from a skimmer.

Live rocks give birth to lots of little critters, you should see the life at night after all lights are turned off. All types of weird bugs and critters run around the aquarium, but like nature they all have their job from cleaning to feeding.

also live rock for salt water is aprox 1 lbs for each gallon. So 100 gallons has 100lbs of rocks to balance water and life. its makes for allot of life the only plastic in the aquarium is turbines for current, skimmer and glass heater. the rest 100% life
