I have two plecos. One is a lot bigger than the other and they have always been okay with each other. However I noticed this morning that the smaller one has got several patches on its body that weren't there before.

I can't work out what is wrong with it. Is it likely to be that the bigger pleco is attacking it - or is is a disease of some sort?

Is there anyway we could get a picture of your pleco?
And your water parameters please(ammonia, nitrite, nitrate)
Thanks

It would also help if you could give more info on the fish--is he still eating? does he have clamped fins? is he acting strangely in any other way? what color are the patches? how big are they? have you noticed any territorial behavior?, etc.

What type of pleco is it? I don't normally associate plecos with attacking, but I guess anything is possible
