I picked up a 210g tank 7'x2'x2' a few months ago and will hopefully be setting it up in a new house in the next 6 month or so. I've also been a piranha guy but have been out of the hobby for 4-5 years now. Right now I'm leaning towards picking up a big shoal of Caribe piranha or a mixed shoal of piranhas, but with a tank this big I know that I have many options of freshwater fish to keep.
My question is, if you had an empty 210g laying around what would you suggest keeping in it?
