Aussie clarkii clowns

Aussie Clark´s of this thread......belongs to the same Variety founded in GBR and Solomons............

Its a Coral Sea Realm.........

These Black are Melanistics...........

Founded mainly in Stichodactyla mertensii............

Only in the south west Coral Sea (New Caledonia and Vanuatu islands)...........exists a different variety.........

But South East PNG..........GBR..........and Solomons are the same variety......


Remember that in the late Pleistocene Era...........during the last glacial maxima.............the sea level was 140 mts bellow actual level............

And Australia was conected with PNG...........forming a Continent called Sahul..........

This variety was isolated in Coral Sea............


This pictires from Sustainable Aquatics.........I suspect that they came from West Australia............called ABCC - Australian Black Clark´s Clownfish.......

They have different band shapes............and the yellow color of the tail is a bit transluscent..............not solid Yellow as seen in the other varieties...........

Try google with Exmouth / Ningaloo Reef..........this is the Geographic range of this variety..........

And if someone find this in PNG..........maybe is in the extreme South West...................

But I never see pics from this variety there..............never...........

All my pictures findings was in Exmouth/ Ningaloo reef.........

Thet seems to be one of the rarest variety...........due a small geographic range..............

Awesome fishes............

So my first 100% impulse buy in many a year......

I've always wanted blue stripe bicinctus, but have never seen any, and doubt I will at this rate :rolleyes: . Then I saw some clowns at a LFS, labeled as Aussie Clarkii Clowns. Simply stunning! I bought them. Seriously considering a new tank for just them. Anyways, anyone else seen Aussie Clarki's before?


Excellent clowns Which fish store did you see them at
 
Yellow Pelvic and Anal fins in Clark´s.............. of all varieties...........means that they are hosted in Entacmaea quadricolor............or Heteractis crispa.......

When these fishes are hosted in Stichodactyla mertensii...........their Pelvic and Anal fins turn Black.........

The snout in most of the cases turns grayish..........

These are Melanistics........from Indian Ocean variety.......from Original Description.............compare with the video #2 hosted in BTAs.........

They belongs to the same population (Indian Ocean)............but fishes hosted in Stichodactyla mertensii..........have black Pelvic and Anal fins........


Sorry if this has been mentioned already but what anemone serves as a host to Clarkii clowns in Australia?
 
In great percentage of the pictures they are founded in Heteractis crispa and Stichodactyla mertensii...........

Here is a picture of them hosted in Heteractis crispa.............near Madang.......PNG.........

South East PNG fishes belongs to the same kind of Clark´s from GBR..........

Ok. Reason I asked is my back clarkiis (presumably Australian lineage) ditched their green bubble tip anemone like it wasn't even there and moved into my new Haddoni pretty much as soon as I added it to my reef tank. So I thought may be their origin had something to do with it.
 
It seems that they like Stichodactylidae family.........than Actiniidae.......

But they are founded in all host anemones in the wild...........including Cryptodendrum adhaesivum..........

Frequently they start settle in Nursery Anemones.........such Beaded Anemone Heteractis aurora........or Macrodactyla doreensis..........

From Magang - PNG

BTA´s in this region is often ocuppied by Amphiprion melanopus or Premnas biaculeatus............

Some times Amphiprion clarkii use these anemones as host..........like this juvenile.............

Yes.........Clark´s is a fascinanting group.........and they have unique Biology..............

And also there are 10 different varieties............each one Geographically isolated..........and showing unique features............

5 of them have Yellow Tail..........and do not show sexual dichromatism......3 of them founded in Indian Ocean..........and 2 in Coral Sea........

And 5 of them have White Tail..........and 3 of them show sexual dichromatism.........one founded in Wallacea to Ryukyus.........one in Caroline Islands.........one in Marianas.........and 2 in Japan Izu...........and Ogasawara.............
 
I guess a bunch came in, since right after I got this one, my buddy from the LFS said they have one too, just as nice.
