How do I get fish into my aquarium in my room?

The only fish you can add are special fish with a blue star next to them on the card. Unfortunately, at the moment there's only one you can catch at the moment (a jellyfish, and even he is hard to get!!). You can get him from the fishing area where there is an event going on (it is at the top of the list of places, but right now all the rooms seem to be full all of the time so you'll have to wait a while!) 

Special fish are white and a rainbow appears when you catch them. There are six in that area at the moment, and only one is keepable, as I said. There were more in another fishing area in a previous event last month, but I don't think you can get them anymore, unfortunately. Right now the event area is your only bet.

For 100 ameG, you can buy bait which helps only special fish come to your rod, but if you don't have ameG, you might get lucky and get some of the bait from time to time.

Hope this helps!

Here's what the fish look like on the card...



Good luck!
