Good or Bad: Polyps or something?

[amhealy]

Here is a picture of my tank: http://www.amhealy.com/aquarium/Reef%20Tank%201.jpg

The goni is in the center of the tank near the bottom, sitting on a rock.

Do goni's not like being on a rock, maybe? It's not by any other corals or anenomes.

What should I do?

Also, I know my iodine level is a little on the low side.

I stopped putting the liquid food in that I was told to buy because someone said I was feeding my corals and anenomes too much because my nitrates were high or something.

I'm really glad to know that it's a pineapple sponge and that it's okay for the tank. Even my LFS didn't know what it was.

I'll go do some research, but how does sponge grow in a tank? Where does it come from?

When you get a chance post your parameters and what lights you're running and maybe somebody can help.Iodine isn't important to a Goni as calcium so make sure you check that.Usually when they are starving they receed around the outer fringes.They also need to be spot fed 2-3 times a week.I feed mine cyclopeeze,oyster eggs,and mysis.They are slow eaters so if your flow is to high,you might need to turn off the pumps.Its possible that the anemones that died might of cause the problem.Gonis are susceptible to brown jelly infections so make sure the polyps are able to expand and if you ever decide to put it on the sandbed make sure none of the polyps get buried.

Sponges are usually hitchhikers that come on the live rocks people buy.They are filter feeders getting there nutrient from the water.

Post parameters(ammonia,nitrite,nitrate,PH,calcium,akal inity,SG,temp.)would help,Good Luck

I don't know if I said thank you. That is what they look like, and I'm glad to hear those are safe.

P.S. Just looked and I did say thank you, but now I can't delete this post.

Thanks. I'm going to do all the testing this afternoon. I'll also post about the lights and all that.

Flower pot corals are notoriously difficult to keep... Some debate whether they should even be sold for the hobby. Once you post your water parameters we can probably help figure out what's going on.

they are hard coral to keep but seen many other reefers who keep them successfully and they get very large in there tanks, matter a fact i have one buddy who has a black clown fish that host his and you cannot go no were near it in his tank without getting attacked. The tanks i seen them in were big systems with 100 gallon sumps big calc reactors, skimmers, auto topoff systems.

I think Gonioporas are getting easier to care for today.People understand there needs better than they did in the past.It seems like the stigma about them will never die.IMO,if you find a healthy specimen its survival rate is good as any other LPS.

Those little sponges are normal to a new system,They show that its actually maturing like it should.
Cant comment on the Goni,cause I never tryed them.
