We haven't had fish in over 30 years. My husband had them as a child so we had several tanks for years, then I had a child and suddenly realized that I was the one taking care of them. So 5 tanks went down to one in about 2 years and the last one was a 30 gallon tank and we had an Oscar - those bad boys eat anything and everything. It drove me crazy because I would feed them and that fish would leap out of the tank at me. Once it landed on the floor, I walked off my DH rushed to his rescue, said I was killing Oscar and my response was, "I hope so!"
I loved the Angel fish, they were always so graceful and pretty. But other fish would gang up on them.
My DH didn't have time to take care of the tank, I was pregnant with my second daughter and we decided no new fish. When my neighbors said they would love to have the fish and all the tanks we were done.
Watching fish can be so relaxing - until they start eating one another and then not so much.
