 Topic: Random Coral Question
Posted: February 24 2016 at 10:36pm |
|
So I'm not sure what this coral is called but It has a smooth tree trunk like body and at the top it opens up to tentacles like an anemone with a mouth in the center. It's only 1 inch tall right now. Anyways I was watching it today and every so often it would spit out a dark brown chunk that looks like a peace of food. What would you guess it's spitting out? Is it eggs? Or do corals defacate? I was so intrigued and curious as to what it was doing.

Sounds like you spend a lot of your free time in front of you tank.  From your description of the coral it could be a Palythoa, perhaps a Palythoa Grandis or as we call it, the Blundell Button, named after our own Adam Blundell.
On the other hand, these button polyps like to eat fish poop. Not long ago I saw a poop pellet leave the fish and fall on a Zoanthid which promptly ate it.  I know, that seems sick, but it's the Circle of Life. I've also seen fish pick at coral waste.

Coral do just fine without supplemental feeding.
I would definitely not be feeding that Duncan. This new tank cannot handle the added pollution. How do I know this? Well, I've been at this hobby way too long, started up way to many tanks and I've seen way to many new hobbyists go through what you're going through. Aloha, Mark

I feed my Duncan's when I feed my feed (they eat whatever the fish eat but I spot feed 2 or 3 times a week.). A couple pieces of mysis spot fed to a single Duncan head isn't going to polute the tank, but you notice a huge increase in growth.

Okay, I'm going to try and explain in more detail why I am saying not to feed the Duncan. I'm looking at the pic. I see rock and sand that are totally bright white. I see a brand new tank that doesn't have enough biofiltration to handle extra food without suffering water quality issues. In another thread just this morning I have specifically suggested some Macroalgae for this tank to eat up the pollution and keep water quality good for the coral. Water quality issues(Nitrogen pollution) would be worse on the Duncan than not getting some supplemental feeding. I also see a Duncan with a dark stalk. Maybe it's mostly shadow, but that darkness can be an indication of insufficient biofiltration/poor water quality. Good water quality also includes things for which we cannot test, so we use a general phrase "tank maturity". It takes time and patience. Most Coral are animals that get much of their food via photosynthetic Zooxanthellae Algae. They will be okay without extra food, while the biofiltration grows more substantial over the following months. Then feeding can be resumed. I know that feeding the coral can be an irresistible temptation at this point, but overfeeding by new hobbyists is one of the most common problems. Also, remember that this is a hobby where patience pays off in big dividends. Aloha, Mark

It is dark around the base like it has been fragged (top portion is shadow) I bought it like that from the store but it is Thriving in my tank! I'll have to post pics of the other corals I have to see if you think I shouldn't even feed them. Unless that's what you meant was don't feed anything but fish at this time.

These are the other things in my tank. I'm sure you might think I'm crazy for having an Anem. But I have had it a few days and it is Thriving!

An anemone!  Now I'm even more certain that I said the right thing about the darkness on the Duncan frag. I see a couple other coral that can be very difficult to keep in a tank as new as this. Which ones do you think I might be thinking of

 This is a face of approval for what you said. Previously I mentioned that feeding more than the new aquarium can handle is a common problem for new hobbyists. Another common problem is that they get impatient and move too fast for the good of the animals. Could this be you on both counts?
I'm getting the feeling that we ought to ask about fish. How many and what kind of fish are in this new tank
Water changes, are they large and frequent? Since Macroalgae is not yet growing in this tank, frequent large water changes is the only thing that can save the animals.
Aloha, Mark
P.S. Current tank pic?

The only other photos that I have are in the Facebook link below each of my posts. The only fish I have in this tank is 1 Ocellaris Clownfish. The sick fish did die  . But e verything else in the tank that I have is thriving! That Duncan coral has nearly doubled in size.
