white spot

[hwcheong]

Hi,

Everytime I add in Tang, and after a while I can see white spot on his body and this does not happen to other fish. And I failed to keep Tang until now. Any one can advice what should I do to prevent this ?

What tang have you added? Waht other LS do you have in the tank?

tangs are ich prone. maybe u cna try quarantinning ur fishes b4 u add them into the tank. if cannot quarantine den leave it there in the lfs and observe lor, see whether it can feed anot, den see if its alert to its surroundings and whetehr there';s enuff flesh between the brows.

When I 1st started having ich problems, I soaked my frozen food mix with garlic guard for 15mins b4 feeding. Regular feeding in dis manner I find that I dun have any ich problems so far. U might wanna try it out too.

I had 3 tangs now, scopas, yellow & powder blue.

Damsels, clowns, angels & wrasses are more hardy and usually will develop some form of immunity to ich. As for the tangs, they are usually more prone.

When you don't see white spots on your current fishes, it does not mean that ich is not present.

Ich have 3 life cycles:

1. Attached to host (appearing as white spots on fishes)

2. Hunting for host (swimming freely)

3. Buried in the substrate

For your condition, I gather that the ich is already present in your tank. It periodically feeds on your hardy fishes but due to their immunity, it does not cause a outbreak.

When you add new fishes that are more prone to ich, it causes an outbreak thus you see whitespots.

Generally speaking, the Zebrasomas sp (ie. yellow tang, purple tang, scopas etc) are more hardy as compare to the Acanthurus sp (ie. achielles tang, powder blue, powder brown etc).

And when a yellow tang cannot survives in your tank, I would suggest you improve on the condition before trying another.

There are only three proven methods of eradicating ich:

1. Formalin

2. Copper

3. Hyposalinity

The former two methods are very effective but can only be use in a FOWLR (fish only with life rocks). If you are having corals in your main tank, you can only use Hyposalinity.

However, please note that Hyposalinity can only be perform outside of your main tank in a QT tank. While you are doing hypo, you need to have a fallow (without any fish) main tank so that the ich in the your main tank will not be able to have any host (immune or not) and will die - this treatment will take a minimum of 6 weeks in order to be effective.

Juz to share...

for me, i add a couple cleaner shrimp.

I have three tangs. Regal, Brown, Yellow Tang in my 4 ft.

Initially, the brown tang has white spot. I caught it. Dip it in fresh water twice a day. In 3 days, the spots are gone. The fish is very healthy now.

ONe more thing, if the fish does not die of white spot, it will be stronger and resistant to the disease.

Garlic is a good preventive measure IMO.
