Black Spots on Percula Clowns

[Mort]

The past few weeks I have been noticing these black spots on my Perculas.
They appear to change in shape, size, and position.

I am not aware of any diseases like this.

Anyone familiar with this situation?

TIA

[RicSeyler]

One of my Percs has had black spots and patches on him for over 9 months.
I looked around for any info on this but never found any. He has always
seemed
fine, but discolored. So I'm curious too.

I don't know if it helps much, but I took a moment to look up Black Spot
disease in my fish books.

"The Manual of Fish Health" (Tetra press, 1988, Drs. Andrews, Exell and
Carrington) focuses primarily on freshwater however they do have an example
of black spot on a marine fish. pp 178-180 describe the disease with small
black spots which can measure up to 2mm. It states that the cause of these
spots is form a tina larval parasite and that small numbers do little harm,
usually consumed by the fish's immune system through time. Large numbers
however are unsightly and may be dangerous to the fish. It continues to say
that the occasion or frequency of this disease is rare since the larval
cycle involves birds, snails and finally fish. Most aquariums won't be
subject to this cycle. An effective treatment is not described by this
book.

My second text, "The Marine Aquarium Problem Solver", (Tetra Press, 1996,
Nick Dakin) has a short listing for Black spot on page 72. It describes the
spots as being small (1mm) on the body as well as fish flicking and
scratching. It relates them as not being so deadly and makes a note that
Surgeonfish seem to be particularly vulnerable. Treatment is decribed as a
copper based medication or Trichlorofon based.

Other than that, I don't have much else to add. This doesn't mean of course
that your fish are subject to the Black Spot disease I found in these
references, but perhaps I can stir an idea or two to help point you in the
right direction.

My old percs has this black almost fungus like growth on them, seemed to
effect the slime coating.
The patches could be huge, coveing whole sections of the fish.
I had the pair for 10 years but eventually lost them with a few weeks of
one another.
I picked up a paor of clarkii clowns recently and these two came woth
the same disease.
Anyone over there senen this stuff before?
What can I do?
The system they came from and mine are both quite good, their now in an
SPS tank so perameters are well with range for fish, there are no
predators and heaps of hiding places.
they share the 4x2x2 tank with a coral beauty that's it.

The Black Spot you described is no that on Clowns at all. We had a long running threads on
a number of reef forums

Almost all of these black spots on clowns are caused by a change in the pigmentation to
melanism, caused by brushing up against various anemones/corals and getting stings.

OK then how do we treat fish 'scalerotitus'?
It looks terrible. The clarkis have BTA hosts, I thought these were an
identified host for the clarki.
Does it effect the fishs health?

That makes sense. I have a few zoos and mushrooms in my reef. Hopefully
the spots will go away.

Thanks Boomer

"Does it effect the fishs health?"

No, and it is quite common on clowns, especially percula and ocellaris.


"The clarkis have BTA hosts"

Yes, plus 9 other species of anemones but you do have other stings animals correct ?

Then there is the issue of the Clarks itself. This fish has a habit of changing color
depending on anemone. Clarks are know to go from the orange phase to the black phase in
hours when they change host. Your tank is not a reef so there me be some type biochemical
confusion going on here

The clowns are now in a tank with SPS and the anemone.
They came from a tank with fluffy mushies and zoo's which is likely to
have caused the problem.
Thanks for the info.
I hope this stuff goes away soon.
