They could have been dead when you bought the frag. I have a few dead colonies about that size on some of my live rock.

Sponges will die when exposed to air(but only the ones you want).but all sponges feed,If you have a high nutrient or older system they're just chowing down.Here's something I've done(if you have the means)pick off as much as you can, put the frag in your salt mixing container for a week(lit, heated, and circulating).The new salt water is essentially devoid of anything a sponge will feed on and should die off.Zoas will be fine.

its a sponge that grows on zoanthids i have all kinds of it in my grow out system , if left alone it will smother the zoas and kill them , besides that they are harmless and photosynthetic.

overtime it can weld liverock together(found this out the hard way lol)

Well guess I know who I got it from Kidding.

Okay well how do I rid it...Denny or do you just leave it, I think its sort of sweet looking. but one frag I can deal with if its hits them all i'll pull my hair out.

Most def could have came from me, result of feeding large amounts of phytoplankton and I meant not photosynthetic, it grows in the dark and filter feeds just trim it off and slack back on the nutrients mostly harmless

Now that you mention it I will add however my nitrates are quite low but I have been spot feeding all my corals with phyto and the melt off of the food i've been feed which name escapes me right now. mrhasan did a post on it recently grr... my memory is going down hill!

[reefwars]

Ocean fresh pacifica plankton great food I use a lot of, its def the phyto sponges love it

[HaZRaTTy]

Thats IT! haha sorry pure this was in response to denny on the food

They are very easily pulled off with a razor just scraping. Tunicates I looked at and did some research from my understanding tunicates have a outer shell and on the tubes there are 2 openings, I also figured tunicates to be much larger! Do tunicates have any movement response when touched or scraped these don't move, don't close and don't FIGHT
