Sponge?

[m3drver]

looks like as the weeks go by on my newly setup tank all kinds of things are popping up. These things look like sponges and appear to not move or do anything else.

Thanks for all the help so far. I'm sure I'll have more questions as time goes on so thanks in advance!

They almost look like some type of polyps. Check this out.

Melosu58,

from the pics on that site I'd say what i have are ZOANTHIDS . I took a closer look tonight and can barley see small appendages on the ends of most of the polyps. and, contrary to what I mentioned in my first post, they seem to open when the lights are on and close at lights out.

Sadielynn,

the tank is still cycling so there are no inhabitants other than what came on the LR.

Ammonia: .25 (for some reason this number hasn't changed in 3 weeks)
Nitrite:0
Nitrate:5
PH:8.4
SPG:1.025
Temp:78.5
Lighting: one 30watt 10k florescent and one 420 actinic florescent.

Agree that they look like unhappy zoanthids.

They may fair ok with that lighting tho you may wish to up your lighting at some point if you want to get more than the hitch hiker coral
As to the ammonia you may wish to either get another ammonia kit or have it cross tested to see where you are , ( I tested mine weekly and took samples in to diffrent stores biweekly to cross test) If you have cured rock that number should start to decline here soon ...

I was gonna say zoos also...Are they always closed up like that?

yeah, the tank is still going through its cycle so I imagine they'd be stressed out.

My intentions were for a FOWLR tank. so as far as lighting goes, I'll have to keep the lighting that I have for the moment. but maybe replace the Actinic with another 10k. or do the Zoas need the actinic? I have been looking at a CF retrofit kit as well 96 Watt Bright Kits .

I was getting a bit suspicious of my test kit too. I'll head to the LFS tomorrow and have my water tested there. thanks for the tip.

Yep pretty much. I might catch them a bit more open at times but thats about it. they are tiny and new ones seem to be appearing every now and then

Ammonia not moving in 3 weeks. I'm really concerned about that. Either a bad test kit or something is still dying. Dunno, but 3 weeks???

look like sponges to me too. good luck finding an id on a sponge, sponge guides are hard to come by.
