IMO, it looks like the dots are too evenly spread out and they look like they are not rased from the skin ; more like they blend with color. So, no, I don't think its Ich, but maybe someone with more experience with Ich can help more.
remember that plecos (or pl*cos) can change color depending on what mood they're in or what surface they're on.
ps. WHATS the big deal w/ calling plecos pl*cos?!
I have heard that saying pl*co is a curse that if you have one that it will die. Maybe someone is just yanking my chain but I don't have a pl*co but then again I will take no chances being the supersitious person that I am! :
SORRY SCU! Looks to me like it's just the coloration, if it's not raised up I wouldn't worry about it. And like someone said before some fish do change colors depending on mood. It's like Humans BLUSHING! or maybe not. Anyways looks good to me, not like Ich.
