The above link takes you to a youtube video of my fish behaving oddly.
Could you please help identify and give advice as to how to cure it?


I will add that just before this happened all of my fish suffered from white spots, but after using medicine it seems that all other fish are ok.
This one (and 3 other of the same species) now again seem unhealthy.


All help will be appreciated!

Is it a guppy? What size tank are they in? How many fish in it? Water perimeters? Diet, how often, and how much? Can you post a full tank picture? I am assuming the white spots are ich. Do you have pictures?
