help identifying corals growing in my tank
 
Can anyone help identify these corals (i think they are) that are growing in my tank?

setup 6-8 weeks, 15kg fijian live rock, liverock filter, 180 L 47 Gal jewel tank with 2 x t8 bulbs. I have a blue damsel and a domino.

Would like to know how I can make the most of them, food, placement , light, aggresiveness etc...

This is my first tank so I am a complete beginner.

Any help would be much appreciated.

The first one appeas to be a button polyp. You can find some good information about them here:

These appear to be a species of fuzzy mushroom. You can find information about them here:

I have found that sometimes the domino damsels will pick at some types of corals, but in your pictures all look very healthy and like their needs are being met just fine where they are now. If these came in on the rock (which is likely to assume), you got a good bargain. Around here those fuzzy mushrooms sell for about $26/each and the polyp, even a single one like that, would run at least another $10.
The important things to do now are to watch water quality, esepeially calcium levels, which is what a lot of beginners miss. Good water quality and scraps from the food you feed the damels, and keeping the lighting in good shape (replace your bulbs at least once/yr), and they should thrive on their own.
I want to ask, I'm not familiar with the Jewl setups, they aren't available here in the U.S., but does it allow for a skimmer to be used? If so, I would strongly sugget the investment if a reef is where you're headed. There are a lot of oils and protiens in fish food, and without the skimmer to remove those, you will end up doing it by yourself manually, which is a pain in the butt! Depending on how fast it builds up (each tank is different), you could need to skim daily with paper toweling to remove the "oil slick" from the water's surface. If that oil slick is left alone, it will soon suffocate everything beneath it, including your fish. Those protiens will prevent oxygen return in the water.
Outside of those few things it sounds as if you're off to a great start. May I ask where your spg/salinity is at? This is something also needing to be closely monitored, as corals will be affected by fluctuations quite easily. You'll know if the corals are happy by how open they are, and how often and how long.

Thanks for the reply Dawn, I have a Deltec MC500 skimmer and am running it every 2-3 days, I did have 3 of the fuzzy mushrooms but unfornunalety we had a black out which meant the heat was off for 16hrs, 2 are looking a bit worse for wear now.

The one that you didn't identify I only found yesterday, I was adding more rock to my filter and when I took a small peice out it had about 15-20 of the of them on it, I have now put it close to the surface to get the most light, not sure if this is the right thing to do though as it seems to have developed well in the dark of the filter.

not sure what you mean by spg/salinity?

They can be quite resilliant if you give them time and keep track of water params, light, etc.

The one that you didn't identify I only found yesterday,
Did I miss one? I saw 1 button polyp and 2 fuzzy mushrooms. The one mushroom appeared to be fully opened and thriving, looking almost like it is turning inside out as it reaches over the rock.

I was adding more rock to my filter and when I took a small peice out it had about 15-20 of the of them on it, I have now put it close to the surface to get the most light, not sure if this is the right thing to do though as it seems to have developed well in the dark of the filter.
I would put them back down towards the bottom, both the polyps and mushrooms can burn/bleach out if they are too close to the light source. Both of those animals tend to thrive best near the bottom, especially in a shallow tank.
not sure what you mean by spg/salinity?
spg/salinity is the measure of salt in the water. This is done by using either a hydrometer or a refractometer, and is going to be the single most important and needed tool in keeping any saltwater tank healthy and thriving. Without this there is never any way to know how much salt content is in the water, and both too much salt and not enough salt can be deadly to the animals. Optimal conditions for the animals you are keeping is 1.023 - 1.025. A refractometer is a bit more expensive, but also accurate. Hydrometers can be off by quite a bit. I usually suggest to anyone with a hydrometer, find someone who has a refractometer and have them calibrate it for you so you know for sure how accurate it really is. Most hydrometers are off slightly, but I have seen quite a few that were off enough to cause major problems in the aquariums.
