it is very hard to tell by picture wether or not that is ich or velvet.
Velvet (Oodinium pillularis)
Behaviour.
Gasping for air, with very rapid respiration, most typically on the floor of the Aquarium, but sometimes at the surface, are nearly always observed. In the early stages of an infection, "flashing" or rubbing & scratching are often indications, as the fish tries without success to rub off the irritating organisms.
Fins.
Fins can become clamped and folded.
Body.
The most observed feature of this infestation, is a salt & pepper effect of hundreds of small dots, usually with a pall or colour of gold/yellow or rust , which give the appearance that the fish has been covered with a special form of talcum powder. It is sometimes difficult to see this unless the light is coming from the back, & glances off the fish, when it can easily be seen. This advanced phase of infestation is however almost invariably fatal, & the Hobbyist should try to become aware of the earlier signs if he/she wishes to be able to take meaningful prophylactic action.
Gills
. Excessive mucous will be a sign that the parasite is attacking the gills, & a smear as often described previously should easily confirm this.
Skin.
The skin, becomes "dusted" with hundreds of small raised parasites, giving a colour which according to the variant of the form encountered will be from a yellow gold colour to an almost red shade.

Identifying Ich
White spot cysts, each containing an active trophont, appear as small white nodules on the skin, gills and fins, giving the fish the appearance of having been dusted with salt. In a confirmatory skin scrape the trophonts appear as dark round objects slowly rolling around. The trophonts vary in size, up to 1mm and are considerably bigger than most fish parasites. Other features sometimes seen are a lighter, horseshoe shaped nucleus (seen in the top photo) and short cilia covering the entire body (seen in the movie clips).
In the early stages of the disease, fish are likely to flash and rub against objects because of the irritation. At a later, advanced stage they will become lethargic and spend most of their time sitting on the bottom.
