I've been wanting to get a bigger tank(between 60-75) but I'm moving into a still unknown apartment in 2 months and I heard a lot of apartments don't allow anything over like 20 gallons? Is this really true? Anyone ever had any problems/experience with this?

I know I could just set it up and hope they never have to come in for any maintenance or other issues, but I'd hate to get it all setup and running for months and then have them force me to remove it or move out.
