I've been looking into getting an Oscar for awhile now, and picked up a nice 75 tank and stand. Now I'm reading 75 is the absolute minimum, and that kind of scares me. If I step onto an elevator, I hope its got more than the absolute minimum tensile strength to hold me suspended above 9 floors. Is 75 minimum for necessities of life, or is an Oscar going to enjoy a 75. Earlier today I was looking up a couple fish to put in with one, now I'm wondering if my tank is going to be a good home for just the one fish. Anyone out there keep happy Oscars in tanks of this size?
