Nothing added to tank since '09, Ick appears

I don't see what's the big fear of treating fish with copper? I find it much easier than hypo. Good luck on what you decide to do. And your fish collection is amazing as well!
 
I agree with what Chris outlined above. Large angels (which you have a number of) are all about aggression even in a large tank, the only way around that is having a lot of escape caves etc. Unfortunately your aquascaping is very open. In my experience stress eventually manifests itself as a disease, "ick" being one of the most common.

The only reason I mention this is because it's pointless treating the tank if the underlying "stress" problem still exists. That's a lot of work to treat the tank if your going to have the problem crop up again. Many fish carry the parasite but are able to live with it because their fat and happy, but watch how quickly it breaks out if they are subjected to any harassment.

My solution would be to add more rock and provide more escape holes,
good luck.
 
I wish I had a way to put a video of this tank online to show you guys how mild-mannered this fish are. Over the years I will admit that I have had to remove some fish because thay did not get along (including two Emps). They are all plump and swim around the tank causually. they only get into a frenzy when I get close to the tank because they know it is feeding time.

I have had these big guys together since they were small. I never buy full-grown adults and I think I am pretty successful getting harmony in the tank. Even my tangs get along.

There is definitely a pecking order:
Queen is the boss, followed by the Scribbled (surprised?), the Blue Ring, and the Blue Face.

I respect all the opinions but I am reluctant to agree that my stocklist is the cause.

Tank is at .015. Should have it at .009 by Friday. I was due for a water change anyways.
 
If you were wise, you would stop with the "but this" and 'but that" and listen to Chris.
 
I have four species of angels and two tangs in my reef. As soon as the lights go out, you can't see any fish, they hide in caves in my rock work. Have you observed your fish at night, because from your photos it would seam they have no caves to hide in. In other words there could be problems occuring when your not observing. Just trying to be helpful, with some thoughts.

Thanks Obi Wan. Some of you guys are really arrogant. We are talking about fish, not World hunger.

I started this thread to find out how Ick may have surfaced in my tank after months of no new additions. I wasn't looking for aquascaping critiques.

I have noticed on this site that some members have tanks that appear to me to be way overstocked or have just as many, if not more, stocking "conflicts" yet they don't get this kind of criticism. One, for example, would be the 11' tank of the Rc member down South.

Thank you guys for the input. I will take it from here.
 
I don't think a little bit of ich necessarily indicates a need to treat a DT or set up a whole tank QT if the fish are otherwise healthy and eating well. A bit of ich is often, however, an indication of stress, especially if you QT'd your fish and there were no recent additions. Once the stress is resolved, the ich will usually go away, if fish are healthy. I consider something like this a warning that the tank environment needs attention. Could be:

water changes/water quality improvement
diet needs to be diversified/improved
aggression/territoriality among fish
stress due to lack of hides (even if fish are not fighting)
stress from too much noise/activity in tank room
etc.

Some people have mentioned they think you may need more hiding spots for fish that can be territorial and like to have caves. I wouldn't take the aquascaping suggestions to be anything but ways you might consider to reduce the ich. The idea that stress is behind it is valid.

I've had ich show up in my long term established tanks periodically. Thankfully, not too often. There has always been a reason for it, that once resolved, resulted in the tank being healthy again.

Most of the people posting are honestly trying to give you good advice. Whatever you do with your tank is up to you, but don't take sthe advice personally if you disagree.
