I have had this tank in the same location for 6 months now. I recently acquired panda garras in my 55 gallon baseball diamond shaped tank. I have two couches that are touching the tank. After I had put the new fish in, I joked with my dog pointing at the fishtank. He went nuts. Now all my cocker spaniel does is press his nose against the glass. He does this every single moment he can and will not listen. He would rather stare at the fishtank then eat bacon. I don't know what to do. I cannot move the fishtank. (It is way too heavy for me) I have put a blanket over the fish tank's front. He figured out he could stick his head under the blanket. Now I have bungeed-tied the entire tank. He gets under the blanket and the bungee cords. Its not even the panda garras now. Its all the fish. He bites at the glass. Its a sturdy tank. There is absolutely no way he can tip it. Also, he usually listens to me and obeys my commands. He will not now. I am worried about the fish and my dog. Any suggestions?
