I love the video in my sig, i try to watch it often and others like it to keep me in the real world. I am glad you watched it, if only one out of a million people who visit this site ever see it, its worth it to me!
Maybe ownership of the property will change hands again soon....
If you are moving as soon as next january then make due with the 75 gallon limitation as best you can and try to move to a place that doesnt limit you. When i signed my current lease and we paid the pet deposit for our dog i asked about my aquarium, they said that it was a non issue, I asked if size mattered because i had a 240 gallon tank at the time, they said it didnt matter. the property manager came over several times and loved the 120 inside the front door, and the 240 in the dining room. He hasnt seen the 520 i replaced the 240 with, or the (6) 75's in the garage yet, but I dont think he will mind.
Try to find a place that allows water beds and dont mention fish tanks, and see if having renters insurance changes anything
