New to this...What is this?

Okay long story short daughter's favorite movie is finding nemo I always wanted a salt water tank so I decided it would be a fun hobby to have with my daughter. I did A LOT of research. and 6 months later I suprisingly havent killed any fish (except one 4 months ago I lost the cleaner shrimp). Anyways the other day I went to shop to buy a Cleaner Shrimp and some i bout about 5lbs of live rock. I came home set up my tank and after taking some time with my daughter to watch the fun in I realized we now have quite a few feather dusters and these BRIGHT orange colored ???

They are really neat they either are out and moving like the picture or they're in hiding..

I'm really Excited about it even though I have no Idea what it is but im concerned cause I just have a normal lighting tank. Do I need special Lighting and do I feed the feather dusters and whatever the orange things are?

please and thank you for you help

 

They look like a small patch of sun corals to me.

 

+1 prc look like sun corals, they are Non Photosynthetic so it dosent matter what light you have but they will need spot feeding of meaty food to keep them alive. its best to feed them at the same time w/e you feed them so you can train them to open.

 

They look like sun corals to me too. No special lighting is needed, but they will need to eat frozen food like mysis or brine, which you can get at any pet store.

 

how do i feed them??

 

With a turkey baster. When the polpys are open, squirt a little food at them.

 

is there anything that i could buy that would be easier to feed them with the turkey baster?

 

Welcome to the site...glad to have you. The frozen food suggested is probably the easiest food to feed them.

 

but how would i feed them with a turkey baster?

 

You thaw out a cube of the frozen food in a cup with some tank water. You suck the food into the turkey baster. You gently shoot it at the coral when it has its polyps open. It eats the food.
