This is a Bangaii Cardinalfish Pterapogon kauderni, (Koumans, 1933)
Relatively new to the hobby, this fish breeds very easily in the home aquarium. It a mouthbrooding fish. The male carries the eggs in his mouth till they hatch, then for 5 to 7 more days as fry, before they proceed on their own.
In the header is a leadoff to a series of 3D images, & on Planet Earth, a series of tonight`s Cerus bloom shot by flashlight.
Have a nice day everybody.

That is a very unsettling looking fish, though I can't quite figure out why. I'm pretty sure if I was one of those fry, I'd be leaving "home" as soon as possible.

Morning, KH, I agree with Andi. I'd like to see a side shot of that beastie, too. And what do the symbols say?

I also like the reef-upon-reef shots. The first one reminds me of that elementary school project to grow "crystal stuff", where you add various chemicals to charcoal and it grows blue, green, and other color crusties.

NDD said...

yep, I agreee, a mighty strange lookin' fishie! And stranger yet that mouth breeding business.

I was having some trouble last night doing the 3d thing. Even though I thought I was crossing my eyes and disfocusing like before.

Now this morning I remember I used to download those, and put them up on the full screen which then has a black border around the photo-twins.

I'll try that tonight, let you know how it goes... it is quite the interesting effect once one perfects the technique.

Morning ... I like this little blue one: LINK

Good day, Andif
This fish I portrayed in this manner to throw you off a little.
It is a wonderful fish that takes care of it`s young above & beyond what one would assume a male would do in nature.
The female lays the eggs & is gone. He on the other hand, incubates the eggs in his now, distended mouth for over two weeks. He does not eat for this period of time. Then after the eggs hatch, he lets them swim in & out of his mouth, to which they return quickly, after little, short excurisions, into the wild, but no more than an inch or so.
He still does not eat. I have this on my DVD, which you are welcome to see if I had your address. You can email it to me. NDD, might have something to say about it, as he`s seen it.
I`ll do a post on the fish from another perspective soon.

Knucklehead said...

I`ll be doing a post on this fish soon so you may see it in full body.
You are absolutely right about the symbols.
How did you know?

Knucklehead said...

Yes the technique to view them, once mastered, is amazing in the results.
It takes but a second to see the 3D once you know how.
I`d really like to hear about how you view them, it might help others. I put my finger about a foot away from the center of the image & sort of cross my eyes. A picture appears in the middle, in 3D, while the side ones dissappear towards the outsides. Some may be easier than others. I do these free hand, so they are not exact, but definitely 3D.

Good afternoon, Olivia
The little blue one is the largest fish in my band of fishes. I`d say it`s almost 6 inches long. That should give you a scale to go by.
You can see some Scarlet Cleaners at the bottom.

olivia said...

That's not so little is it ... :)

Knucklehead said...

The image you linked to is18 " high by 24" long in real time.
That matches the length of the fish in comparison to the above dimensions. So relatively speaking, it`s not that little. If the fish was in a thousand gallon tank though, it would look miniscule. hah

Knucklehead said...

I should mention that these fish will grow to be over a foot long. Something that I find strange is when I see small ones. I sometimes see tiny ones that are one inch long but look identical to this one. It would be like seeing an adult human that was two feet tall or one that was 12 feet tall, but look perfectly normal.

olivia said...

A foot!

Knucklehead said...

Yes, a little over a foot. That is probably the maximum length. A fish of that size would need a larger tank than what it is in now but I have a few more years to worry about it ever attaining that size.
It is recommended it be in a 100 gallon tank, for full growth potential & it`s in a 70 gallon right now. I`m still planning my 240 gallon tank. If you remember I might have mentioned, I have a tank in which I had talking fish sing "Stand Up For Your Rights". On the DVD. That one.
That tank is 8 feet long 2 feet deep & 2 feet high.
I`m not done collecting all my parts for it, but I have another 70 gallon tank that`s almost ready for water.
