Ich on selected fish only

I have tetra, clown loaches and yoyo loaches in a single tank. 2 of my tetra has 2 white spots which I am not sure if is ich. Its been now 3 days since i discovered it and they are the only ones who have it.
So either it is just a little scale which is healing up from chasing around or is their immunity system not so good as the other fishes.

Has anyone experience this?

 

Any pics ?

 

Yeah ive had experiences like this before they are possible saying the ick effects the weaker fish 1st and in one of my cases never even spread

 

It may be stress ich? Ich can be caused by multiple things- are your tetras smaller than the loaches or have they been ill in the past? Or do they have any reason to be stressed?

If they are smaller than the loaches (especially given how big clown loaches can get), they may be experiencing stress from your loaches.

Here are some pics I managed to snap up with my mobile.

Same here it does not seem to spread at all. Just 2 fishes having it and it actually dissappeared.

The loaches keep to themselves, they are most of the time in their cave. The only factor which I can think of which has changed is the water temperature where it has come down to a couple of degrees celcius. Does colder water promote ich? Anyhow the ich on those fish dissapeared, so i think im all good.

It can, actually! Water temperature changes can actually cause ich to appear- that may be why you had some appear on your fish. Glad your ich went away though! I would keep an eye on them for a few days as sometimes ich disappears and then reappears with a vengence. But you should be fine! ^^
