Tonight while feeding some baby angelfish my wife noticed something in
their tank. There was a very hard to see "thing" in with the fish.
The thing was much smaller than a human hair and was .25" in length.
It had a bump at one end that I would presume is its head. It was
white all over.

After finding this in our baby tank, we looked at our 75 G. adult
tank. Amazingly, we spotted one of them near the top of the tank. It
was the same as the other, but was .5" long.

The fish stayed away from this and did not try and eat it. (They get
live baby brine shrimp regularly and are used to live foods.)

What is this thing likely to be? Is it a concern? How do we get rid
of these? I'd assume they're more that we're not seeing.

Might be Hydra. See if you can get one under a microscope or high-power
magnifying glass to see if it has tentacles. If it is a Hydra, my book
(Baensch) says they need live food to survive. So you should be able to
starve them by stopping feedings of live food for a while. My book also
says they are only a danger to fry -- not adult fish.
