chicagoreef Posted June 13, 2013 Share Posted June 13, 2013 What is this white blob growing on or over my live rock? I've had my tank for about 4 months now. This appeared about a month ago and seems to be growing in size. Its about the size of an eraser at the end of a pencil. I don't know if its hard or soft - its hard to reach in my fluval edge. The picture needs to be rotated 90 degrees, so the blob is growing downwards. There is a second one that is also growing on the same live rock, also on the underside of one of the rock "branches." Is this a sponge of some sort? Link to comment
Reefer26 Posted June 13, 2013 Share Posted June 13, 2013 Looks like a pineapple sponge! Not a bad thing to have, its a filter feeder. Link to comment
chicagoreef Posted June 13, 2013 Author Share Posted June 13, 2013 Pineapple sponge? Sounds delicious! Could this have come in originally on the rock and just taken a few months to emerge? Or perhaps from a coral frag that I bought? I guess it doesn't matter, its in my tank now! Link to comment
surgicalsense Posted June 13, 2013 Share Posted June 13, 2013 It is a good thing. Filter feeder. I have tones of them in 2nd empty chamber in my NC. Most likely it came from the LR. Link to comment

Cirenus Posted June 14, 2013 Share Posted June 14, 2013 +1 pineapple, you will see them like crazy if you feed heavy or have a lot of nutrients in the tank. They will expand or decline with your nutrient levels. great filter feeder =) Link to comment
chicagoreef Posted June 14, 2013 Author Share Posted June 14, 2013 Cirenus - Ah, that makes sense. I hadn't put in much of any food into the tank for the first three months - and these white blobs were barely there, but they have been growing - coinciding with my obtaining a shrimp and then a fish and actually putting in some pelletes and flakes into the tank.

FlowerMama Posted June 17, 2013 Share Posted June 17, 2013 I have only like 2 in my display but maybe 20-30 of varying levels of smallness in the back. But yeah, I feed my acans, blasto, dendro, duncan and rock flower anemone so more nutrients and more nitrates here as well. Link to comment
BojanMilenkovic Posted June 17, 2013 Share Posted June 17, 2013 That is such a cute pineapple sponge.It is a filter feeder and is a sign of a healthy sistem. Link to comment
