blue/white film on eye?

[Luliyuhrouwn]

I have a brand new (not even home for 24 hours) halfmoon in a 2.5 gallon, unfiltered, heated to 79*. Last night as I was finishing his set up and floating his cup in the tank, I noticed over the top half of his left eye is a blue-white film. Its the same or close to the same color as the rest of his body, which is a light periwinkle. Is this normal or common? His other eye is crystal clear, so it almost looks like a pigmentation issue but its opaque, and I'm not sure if it could be cataracts? I'm a bit concerned, but otherwise he seems very healthy and active.

On an unrelated note, I also have the small aqueon manual (?) siphon, which says its "ideal for all aqueon desktop aquariums" which both of bettas are in. I can't get the dang thing to work. I followed the extremely detailed (sarcasm) insturctions, including both figure a and b, but nothing happened. Anyone else have this siphon? Any success, or is it not worth it?

Thanks

Can't help you with the mechanics, but I do know that often iridescent fish have some iridescence over their eyes. It's not a problem unless the eye swells, looks nasty or the fish is acting like it can't see. For example, this guy:

I'm assuming it is something along those lines, althogh yesterday evening he was sorta clamping his fins a bit. I'm going to see how he does this afternoon and go from there, he may still be adjusting.
