few ick ???

[tmkx3]

have been treating for ick with coppersafe for 3 weeks now. My tang has a single white spot on his fin. The one he uses to swim with(Don't know the technical name for it). Is this still ick? He has been clear of all spots since the third day of treatment. I had to top my tank off with ro/water last week. Does that effect the copper levels. It seems like the test was just slightly lighter when I tested but I don't want to over medicate. Can this be something else? :roll:

If it's a yellow tang, the thing on it's tail is I believe a bone used for (this is what I've been told) mating and fighting. I may be wrong, but there are a lot of smarter people on here that will tell you.

My tang is a powder blue and the fin is on his side not his tail. I proably wasn't very clear lol

What level of copper where you treating at and how often where you testing the copper? What are the water quality numbers and how often where water changes performed.

Generally speaking, two weeks is long enough with this type of copper if the levels where maintained correctly. I would not advise longer than three weeks.

You can check which fin <<here>>. Be sure you are not confusing the Caudal spike at the base of the tangs tail with a common spot. Fin "spotting" can be quite common and not always something to be concerned about. Either a simple bacterial issue, bruising and an abrassion. Water changes will usually clear it up as long as diet and stress are in good order.

Does it appear flat and clear like watered down milk drops of raised off the fin and more opaque?

It isn't unusual for the fish to have a secondary bacterial infection left over from a bout with Marine Ich (Cryptocaryon irritans). The copper may not bother the bacteria.

It would be unusual for a single Trophont to remain on a fish for that length of time, but not impossible. Although almost all Trophonts gorge themselves and become pregnant, then drop off, very few will not dislodge, but just move to a new place on the fish.

Remember you can only actually see only a very short part of this parasite's total life-cycle. When the burrowed Trophont gets into the fish, you can't see it. You can only see it when it has engorged itself and become 'pregnant.' That is why some people think it's gone when they no longer see spots. What they don't know is that another 'round' may be in the fish but so far just not visible, OR, the fish will show spots again when later reinfected by those that just multiplied.
