Wow, you make aquarium keeping an art form!
Makes me think of my moms aquarium. Boy she had an amazing aquarium, and it was fun to help her change the water and feed her guys. I can not remember the kinds of fish she had.... I ll ask her.
The aquarium was broken by me. I was a kid, and jumping on the sofas, which was NOT allowed, and I jumped, expecting to land on the sofa arm, and my head hit the acrylic aquarium stand.
It was pretty brutal, and I broke her aquarium, but the fish were okay. I never was allowed to rough house in the living room again. I still have a knot on my head, I mean I was bleeding everywhere.
Admittedly this was 100 years ago so I don't remember much about their care, but do your fish respond to you at all?
also that last picture makes me jealous, now I want a tank!
