I had a lot of fun doing that fish. Isaw the stamp and I bought it immedietaly. Actually my son is still not in age to eat the eggwhite so it was for the centurion. The bottom of the « aquarium » is made up of mash peas, sliced carotts as algea, and the stripes on the fish were homemade ketchup (you can find the orginal recipe at Sigrid‘s)…. just use your imagination to change this aquarium. I think I’ll try some other things with my niece Agathe this next week. Ihave to think about it!
