I hear you, Kristy. My husband and I have an unspoken arrangement between my animals, his musical gear, and the limited space of our two-bedroom apartment. We've both agreed to ask each other before taking up more space for our hobbies, to try to be patient with each others' hobbies, and to be respectful if the other's feeling a little "crunched" by the lack of space. Frankly, if we hadn't wound up with this arrangement, we'd have nothing but a pathway to navigate from room to room, with tanks on one side, and Moogs and guitars and drums on the other.

(The good news is that, with time, he grows to like my pets, so it's rarely a hard sell to talk him into "just one more." The bad news is that, love animals though I do, I just can't imagine having any less space than we do now, so no more tanks for me... after the 55G I just bought to house the 3 juvies I'm keeping from my axolotls' last clutch.)
