I started dating a new woman last year, and was afraid of bringing her back to my one bedroom apartment with 5 tanks going. I gulped hard, explained that I was a biologist, and that I used to live in a much larger place. See, it was only natural to have all this, and with the windows open it didn't stink too much ("smells like the ocean"). Well, it is over a year later and she now has her own predator tank (lionfish, spiny boxfish, huge hermit crab) and a freshwater holding tank for live food. See, we are not crazy afterall. Well, maybe she is, she absolutely loves her hermit crab.
