Umm, didn't you just put up pics of your brand-new tank about a month ago?

...thought i would try mashing up garlic and soaking it up with nori and feeding it to the tang. I have done this for 4 days now and no improvement (just seems to be getting worse) my water quality is perfect.

Has the tang been eating nori for more than 4 days, or just since you started adding garlic?

Your problems may be related to a very young tank. (Remember Brad encouraging you to take it slow, and enjoy the journey?) As to your water quality being "perfect" - how long since it finished its cycle? A few chromis dying should produce a measureable change in your ammonia, nitrite, nitrate levels, one after the other. Unless you have a really really hungry cleanup crew.

PS - do you know rex? He seems to be on your case...
