Hey reefers, help me ID?

Hey, im new to saltwater, I've recently cycled this 20g aquarium.. and as i was putting live rock in I noticed this plant I think is a Polyp.. jus bein curious. any clues?

(might not be able to add photos since first post so i will add em after this)

 

Some zoanthids! nice hitchhiker, hopefully you ahve some decent lights, they are a coral that is fairly easy to take care of, they need 3-5 wpg to survive and a little flow but other than that just sit back and watch em grow!

 

dang, my lighting is rlly weak... im upgrading to about 130watts in a cple days.. but for now it only has 20watts.. think it will survive?

 

yeah they should survive a few days, welcome to 3reef by the way!

 

thnks for the help!, i hope instant ocean salt mix has enough magnesium and strontium for a few corals.. btw, u should see me postin a decent amount in the near future, this site rocks!

 

Welcome to the Reef!!! What type of lights do you plan to upgrade too, and are you panning a reef? If your tank is coral bound I would strongly urdge you to get Reef Crystals, IO is mainly for fish only tanks. Hope this helps some

 

HO flourecents, or compact florecent.. prolly t8s... i heard not to much of difference between IO and Reef crystals.. i prolly will switch but i will be supplementing my water with calcium/alk and iodide.. and i think thats should do

 

If you switch to RC you will not need to supplement, unless of course you get into sps/lps and the like. How many inches across is your tank? I would aim for a T5 High Output setup, I don't know anything about T8's but T5's are very common and just might be giving metal halides a run for their money. Whoever told you there isn't much of a difference between IO and RC must be new to the hobby.... trust me, there is.
