Help Discus

[sjolliff]

I think my discus may have white spot,
its gone really dark, its got a white grain shape on its body and one on the edge of its gill,
also his lower fins have whit bits on both.

he is twitching now and then and keeps on hiding behind the rocks, one of the other little discus keeps on trying to peck them off.

but it also could be an external fungus as they look abit like cotton wool ish

If it looks like he's been sprinked in salt, and the spots are the size of a grain of salt it sounds like whitepsot.
Spots can look fluffy with whitespot.

No it dont look like like that, some bits on his lower fins have gone today, but he has got to on the other side of his body.
they look about 2mm in diameter and they stick of his body about the same,

they look like little white tags

he is still eating etc
