I have these purple stick’s growing out of my zoanthids colony. They have grown about a ¼†over the last week. Good or bad? I also have some tube looking stuff not too sure what it is
Hey DC, I've got some of those sticking out the middle of a moon coral. Nothing really to mine. I've had some grow on rocks but that's the only coral they've grown "out of". Doesn't look harmful as the moon coral is growing just fine around them. Not sure on the tube looking stuff Sent from my iPhone using Tapatalk
The first two pics look like vermitid snails. They will often extend a long mucous string when you feed. They multiply like crazy. The mucous can irritate coral but not usually a big problem. Last pic looks like hydroids to me.
I have to disagree. I think the last pic is of sponges. I had some similar in my tank in Florida. John
I bet you're right John. Also the things in the first pic could be small feather dusters but I would have thought you would have seen them extended by now. The vermited snails only throw their mucous net when there is food in the water.
I don't think it is a vermetid snail or a small feather duster I have both of them and these look different I'm trying to get a good pic but not having any luck.
My 2 cents, its a type of algae growth. I have seen them all over rocks with no idea of what they really are but the rock would be covered in them. Almost like a hard calcium plant that grows in tubular form. Harmless and can be broken off just by rubbing but will grow back.
Good picture. You're right they have branches, vermited and feather dusters obviously don't. Calciferous algae is a good thought. If they don't seem invasive I'd just manually remove them when you can.
