Hi If you are talking salt -and I think you are.

Salt fish do not develop white spot. They either have it or catch it. Cleaner wrasse can actually try and remove it. It is not a disease like with fresh water it is a living parasite (the two are completely separate)

You need a QT tank and all new fish need to be in there and healthy for at least 4 weeks prior to adding to a community tank. White spot can exist in the gills of fish and not be seen. Buy a fish and getting it home can lower the fishes defence system and the white spot can spread over the fish and to others.

You can't treat white spot in a reef tank don't try. You have 2 options. 1 do nothing. 2 take all fish out for 8 weeks and house them in a Qt tank this should kill it in both tanks. (A QT tank has no substrate, bare bottom).

Cheers. Anymore help. Let me know. Ben.

Whitespot is something I have faced many many times with marine fish, usually with positive outcomes.

As with everything in fish world, you hear different things from everyone.... so without disagreeing.... heres my take on it all.

Its true that fish either already have OR catch white spot.

Both fresh and marine forms of white spot are parasites, with similar life cycles.

Even though this ciliated protozoan parasite is VERY large for a protozoan..... its still usually too small for cleaner wrasse to remove.

They tend to pick at damaged flesh.

Cleaner wrasse are specialised at removing crustacean type parasites like copepods/isopods.

Quarantine is always best solution but even with quarantine, whitespot can get through.

Its survival is not dependant on there being substrate in an aquarium. I come from an aquaculture background and can assure you that not having gravel is no sure fix.

It can be treated in a full reef, the polyp lab product medic is effective in the majority of cases.

Compared to velvet and Brooklynella...... white spot isnt that bad.

Its still horrible.

but you have a good chance of treating it.

I thought that if fish get stressed (tangs) they become sus to whitespot.

Either way im going to do nothing at see what happens

Thanks for the advise

Yes stressed fish are more suseptable.

This is due in a large part to the slimecoat.

Keep in mind stressed fish produce more slimecoat that can lead to small bits of sand sticking to fish and causing what looks like white spot.

Unlikely the case here, but sometimes it can be.

Tang on the sand bed gasping covered in spots, and still that PoS wrasses is trying pick bits off him. I was so angry trying to catch it that my teeth bled :(

Put the tang in the sump so he could get a break.

So angry at myself for not following my gut.

Do you have a pic of it?

A cleaner wrasse can not eat white spot, they are poisonous in the blister and as adults, the cleaner wrasse just taker off damaged bits and other life forms. The leandrites is the only cleaner that will take off white spot.

A pic would help because there are mimic cleaner wrasse that take off chunks and scales; they look pretty but are less then useless in the aquarium. But that being said, I have had nutty cleaner wrasse that just keep bothering the poor fish to death, usually!

White spot and velvet are always in your aquarium no matter what, they are part of the evolving protist community that makes it possible for your aquarium to keep going! Now if your fish or a fish gets an infestation, which is another story. Once breathing is an issue, there is velvet amongst it all, those gills, if they keep working that hard, will begin to fail and that is usually that.
