Field Notes

Description:

ID by nigel.brennan - thankyou ... :)
Body length is about 4cm with a very long 'strands banners'. IT'S NOT A LONG EXPOSURE MOVEMENT TRAIL, they're the dorsal and anal fin. Pectoral fins were round and thick, looked like leaves, Pelvic fins were quite long and splitted. Colour: silver - turquoise - royal blue - metallic light green. Surprisingly, it's a very fast swimmer.

Habitat:

Saltwater

Notes:

Found this 'fantasyland' fish at the surface eating some water bugs in a similar way as a gold fish. It was dark (19:30hrs), could not focus my camera properly.

Special thanks to nigel.brennan, S Frazier and Argybee for spending their precious time on this little fish :) Mystery solved, case closed :)
Well done nigel. In Aus it seems to be called Thread-fin Jack. http://www.oceanwideimages.com/Large-Image.asp?pID=16495&cID=654&rp=categories%2Easp%3FcID%3D654%26p%3D2
I've been searching for bizarre fish with modified fins: strands...but no luck...
Elaborate Siamese fighting fish. But in saltwater?
Yep ... Royal Motor Yacht Club berth No. 74 to be precise :) I touched it's fin and whoooz ... it went down in a flash.
Is the map accurate? Pittwater marina? I'm thinking maybe an escaped pet ! :) Otherwise I'm not very knowledgeable about fish. It certainly is a mysterious looking thing. Did it seem healthy and moving well?
Argybee, you've got to help me with this one :) Do you think it's a juvenile one? I went to the same spot at the same time everyday, no luck :(
Fantastic. I have to follow this one. Can you go back with a good light?
S Frazier, I had a good 5 minutes to observe this fish, it's truly amazing. So gracious and sort of glowing in the dark, too!
Wow. This is a mystery to me. Can't wait to find out!
