A long time ago there was an issue of Dragon that contained an article which had different types of Aboleth in it. I remember that I liked it, but I am not sure what issue it was in. Any help here would be appreciated.
pretty sure you're thinking about:
131 - Greater aboleth, noble aboleth, ruler aboleth, grand aboleth (The Ecology of the Aboleth, Brandon Grist)

I created the Abolich for my 2e game years ago... god the players hated that villian.
Yes, thanks, Boz
