Over the last week or so, I've developed a fluttering in my right ear. Sometimes it does it for no reason, but it seems to do it on command in response to even moderate sounds. Even a dog leash rattling will cause it to flutter in and out in response to each chink of the leash. If I click my fingers next to this ear, 1/2 a second later I'll actually hear a faint pop or click sound in the ear in response.

Could simple fluid in the ear, or allergies cause this?

this is a muscle spasm in the middle ear, look up middle ear myoclonus, stapedial myoclonus and tensor tympani syndrome....you will find your answers there.

Myoclonus is defined as repetitive muscle contractions. With me it only happens one time in response to each loud sound, as if the muscle was tensing hard and releasing. The ear also feels full as if theres fluid in it.
I do get sleep myoclonus (jerking awake when dozing off) fairly often too, so I think I should see a neurologist.

I have had bad anxiety lately as well, and I guess both of these could be caused/made worse by that.

cam,
my myoclonus was not text book either, have not met many that are. a neurotologist is a better bet with this....and yes it does feel like fluid in there, but its the muscle tension.
