med are not a problem, my past experiences with these guys have been that they are fairly resistant to disease in good condition. everyone sees this mainly from an experiment point of veiw, but I was planning to get some discus anyways, and I will actually WANT them after the experiment, and I see no point in wasting money on angels that I dont really want.
I checked out some tanks, I am planning on a 75g now because they are so much deeper.
