I mostly feed frozen foods. Glassworms, artemia, bloodworm, black mosquito larvae, and so on. Slowly-sinking foods are preferred.
So it sure is possible to wean them off live food.
Iridescence is a strange thing. My new paros(also in an ID thread) also show iridescence not visible with normal lighting but only with flash. In these it is blue, but the same idea.
As far as I know filamentosus has more solid red marks, not just iridescence. Also, sp. Ampah has little solid colour. The fish in this topic look very similar to your fish.
What you described is already known with guppies. At places the adults are caught away the fish stay smaller and mature earlier. This is due to genetic change, so evolution. Url: http://www.nrcresearchpress.com/doi/abs/10.1139/f05-079#.URaBLqU0EWs
Unfortunately they really don’t like too much light. I tried all kinds of lighting but they refuse to do anything. These are the best pics they allowed me to shoot with extra lighting:

[IMG]http://imageshack.us/a/img585/2198/p1060691.jpg[/IMG]I tried that, but only the background gets lit and the fish is even darker. The lens is pressed against the glass, and so is the fish. The tank is quite dark, since they like that. I could try adding a lamp temporarily …
I think you should do that. Then start lowering pH. When pH is the right value week a week and then add paros.
In normal aquaria you wait for nitrificating bacteria, which grow very slowly and are very delicate. Most bacteria do not thrive in acidic water, so probably these bacteria also won’t come in high numbers.
I hope this is good enough for identification. Only the first is made with flash, the others are how I see them naturally.

[IMG]http://imageshack.us/a/img834/1569/p1060623u.jpg[/IMG]For paros I wait two or three weeks. When kept right they are hardy fish so one week will probably be okay. It’s a small tank, so you don’t have to wait too long. You won’t get many bacteria in such acidic water anyway, so waiting for them doesn’t really make sense.
Thanks 🙂
I am quite sure it is a female. She only gets this colour when courting. and it is less intense in reality. The flash makes everything shiny 😛 .She also gets the gender-typical pale colouration. Her fins are somewhat shorter than and different from the “real male’s”. Also, I saw them performing “fake spawning”, so to say.
I got them from Thorsten Kolb at the IGL. He breeds a lot of paro’s, he should know how to sex them.I found a trick to making photographing them displaying possible. I put a black carton cylinder around the lens and glued on a glass plate. They now see their reflection and the camera sees them. This way they display to the lens.
Battery wasn’t helping and quickly went dead, so very few pics. I made some more but those were not sharp enough. This is all the same fish. Note the variating distal caudal band colour.

Not sharp, but you can clearly see the translucent band in the caudal fin.

Some baby bintan “Sentang”

[IMG]http://imageshack.us/a/img6/1093/p1060573ig.jpg[/IMG]I finally got the dominant male displaying to a mirror. I tried very hard but it appears impossible to photograph. I will try to draw what I saw.
EDIT:
I put it on a green background to make translucence visible. The parts of the fins with some faint green in it are translucent. The borders between colours are all very faint but that was really hard to draw. This is just to give an idea of the colours that are in it. In fact, there are no distinct colour bands except the blue ones. The others are more vague without clear separation between each other. The white/blue band in the caudal is also slightly translucent.
This looks like a bintan variant. I have two other bintan-like forms(Sentang and an unknown one) which look different from this one in reality.
