The first time I heard that grunt, I was startled. Then it started happening each time anyone walked by in the dark. We called him the Grumperer.
I loved all of the Angel fish. I had multicolor angels, flame angels, and bicolor angels. They are beautiful. Actually, all of the saltwater fish are pretty nice!
I'm wishing I could have a salt tank again, but right now we travel too much. It's hard to get decent fish sitters where we live.
