I have that exact tank. I think your stock list looks pretty peaceful with the only potential problem coming if you choose both sexes. I have a Midas, Jd, Freddy and a Festae in mine with 6 silver dollars, 3 l75's and an l204. The only issue I've had with this stock is the Freddy is female, the Jd is male and they've hooked up. Lol ...The Midas used to run the tank, but my Jd has started to make his life miserable. My Jd used to be the whipping boy, but now that he's got a lady to impress, he's claimed the tank..
I think your list looks really nice though. Definately worth a try. I'd make the Boucourti the centerpiece. Wish I could stock one, but even with 300 gallons, I really don't have the space.
