Aquarium idea?

What do you guys think? It could be a high level furniture, and it would be similar to gardening and planting seeds/crossbreeding etc. except we wouldn't be talking about seeds but fish. Say the aquarium has a 10 fish capacity, we could train and breed fish we have caught in the wild to get even better fish. Fish don't have much use right now, this could boost the utility and could add some excitement to the fishing job (it's the least popular of the gathering classes and the least useful right now) and once gold saucer is implemented they could add some kind of fish race contest lol, would be cool (kinda like in DC2).
