Let me clear the air for everyone. Antique fish tank just means old fish tank. I'm not sure what they were doing in the old days that would make the fish tanks any better. I can't imagine water filtration and water sealant were better quality sixty to a hundred years ago, but maybe Kanye knows something we don't. The one thing we know for sure is that Kim probably threw that fish tank out. We know who's in control of that relationship.
Sad story about fish while we're on topic. My parents had five goldfish that they raised in their outdoor pond for years. One day recently they came out and there were only two goldfish and the other three were terrified and hiding. Something must have eaten them. They got more goldfish so that the scared fish would relax, but then those goldfish got eaten. We could have used an antique fish tank...
