That tank of yours and the fish look very well. Chapeau to you for doing your tank up so well. It is beautiful. I enjoyed watching the film. I saw that there were two fish that were constantly chasing each-other back and forth in the tank. Which fish were these? There are some lovely specimens in there. and You are keeping the tank up so well. Having an aquarium is a bit of work, but boy-oh-boy--you sure do get pleasure from it, don't you.
