Guppys struggling

I am now down to 2 female guppies in my tank from an original 5 just a few weeks ago.
I have noticed for the past wee while even though I am only putting in a tiny pinch of fishfood (aquarian) per day that it doesn't seem to be getting eaten.
My guppies in particular now seem to have become still and lifeless and are backing themselves into positions in the tank where they are wedged and don't have to use any energy to swim.
Just woke up this morning and have noticed that one of my guppies seems to have what looks like flaking skin around the mouth area, I've taken pics but couldnt get a sharp picture which shows this.
My water levels seem fine and my tanks not overstocked I would say

Apart from doing partial water changes has anyone got any idea what is going on or do guppies just see me as Death

 

Do you know what your water parameters are? Ammonia, Nitrite and Nitrate. Also, what temperature is their water at? Flaking skin kind of sounds like ICH. Do they have little white spots all over them, kind of like somebody sprinkled salt on them?

 

It's hard to tell from the pictures, are they losing color on the tails?

 

Hmm.. There seems to be live plants in there? If so, are you introducing co2 into the tank?

Also, I see plant parts in the water. Plant parts will produce ammonia into the water if they are left to themselves. As someone asked, what are your levels?

Scales popping out could be dropsy. Is the fish seemingly swollen? Dropsy is caused by bacteria, if it accumulates enough it will swell your fish and cause the scales to pop out. It's not a disease, however it is caused by an underlying problem.

Have you gone through the nitrogen cycle yet?

Have you tried a different food? My guppies eat veggie wafers, pellets, flakes and blood worms. They'll eat anything..

Please check your water quality and get back to us! Hope it helps!

Unless you're doing a high light setup, co2 isn't needed.
