As far as I can tell, having walked Nova Friburgo downtown area many times, there are not aquariums here. Neither big public one nor little ones for the home. There are pet stores with doggy stuff, and bird stuff, but it just isn’t the habit here to have fish or cats in the home. Maybe its the heat or the humidity or the proximity to the ocean or that if you want a fish here it needs to be a fresh caught – dead one. I did remember seeing fish in the pond at the park of the sitting dog so I went back into my archives to find you a fish story.
