Since fishing was added a while back, I thought it might be cool to have fishtanks players could show their fish off.
-More fish to catch. Just by outright rarity and others based on location/weather/season.
-An item to carry live fish in.
-Repet could sell fishtanks (and some fish types, though the rare/cool stuff should need to be fished manually, promote people going out there and doing it. Fish smuggling!) in various sizes. Little bowls for a single fish, down to room-wide aquariums for corporate show-offs.
-Different sized fish, so people can brag about that huge electric eel they bought/caught. Not sure if fish sizes already exist/matter.
