Guppy acting strange

[Steve2717]

As well as my neon acting strangely, on occasion ive seen a couple of my guppies swimming with the back curved upwards sometimes drifting to a vertical position. This has only been noticed a couple of times and acts normally the rest of the time. Is this a sign of something to watch out for or normal behavior?
Sorry about quality of the photo, hard to get a picture when they're not getting photo bombed by another fish or hiding in the plants

I tried googling it last night and found something called broken back syndrome which can be caused by parasites but as it did it for a short time, could a parasite infection clear up on its own? I had been treating the tank for ich so would this clear the parasites that would cause this as well or just ich disease? Ive been using the kingfisher whitespot control
