A must have!!!

My son and I just love this app!!! Just opened it again today and found a new baby fish, 5 in all. Easy to use and relaxing. The only thing I dont understand is the treasure chest that floats to the bottom of the tank when I opened the app the last dozen times or so. If I touch it, it just vanishes...
UPDATE: make that 6 amazing fish, another new baby just joined our tank!!! I love making them all different colors. (-:
