We all know pets can make us happy. It is why we have pets in the first place. However, there are always rare occasions when the pets can do something make us upset or even angry at them.
I remember when I was a kid, my uncle had a large aquarium with 3 different species of large fish. The smallest one was over a foot long. Then one of the fish kept attacking every other fish and taking chunks of flesh out of them. It pissed off my uncle and he moved that bully into a half filled small tank. so the fish couldn't even stay upright, I bet it was scared in there. After 20 minutes or so the fish was returned to his own tank, and he had completely lost his aggression.
About two years ago, I have had one mean male Dwarf Gourami who believed the tank is his, and he was a big bully especially toward other supposedly territorial fish. He kept picking on my two female German Blue Ram every time they run into each other. He just kept rushing at them at full speed while flaring his fin. As a fish keeper, I know that when fish is stressed from any reason including aggression from another fish might cause illness and even death in the long term. So I wasn't happy.
At first I was doing big movements outside the tank trying to distract him right when he show aggression toward the GBRs. It didn't work.
Finally I moved the dwarf gourmai to his own tank to "teach him a lesson" just like my uncle did with his bully fish. This bully was so scared in that smaller tank and he was staying in the corner for entire two weeks until I moved him back. He was only slightly less aggressive after his return. That didn't work out well. Even though he was my best looking fish, and was born at my home, I was quite angry with his attitude.
Have you ever had such experience that one or more of your pets upset or making you angry?
