I have a basement utility room big enough to hold about 30 55g tanks on racks, but we also have tons of junk even though we've had 4 huge garage sales in the last 2 year. I would love to set up half of that space with breeding tanks for Cichlids and other FW
fish, and heavily planted tanks, then the other half SW
Reef tanks and grow corals and make a business out of it. If I could make enough money at it, I'd easily walk away from any job because I have a true passion for this hobby.
If I won the lottery, I would either build a house with a huge dedicated fish room or buy a warehouse space and start up the business just for kicks and also to employ some fellow fish fanatics so they could leave their jobs too. Ok, I would do both.
