Ok, so, I don't have fish at home. What I have are cats, one white, and red (orange), both Persians. I miss them when away from home terribly.
When we checked into the B&B we stayed at a few weeks ago, our hostess was showing us around, and she introduced us to the resident fish. They were in a big, open top stoneware fountain.
When we got close, they came up to greet us, the white one, and the orange one! They greeted us the same way my babies do at home.
Being Persians they tend not to make a lot of noise, and open and close their mouths to meow, but no sound comes out.
Which is just how the fist greeted us. Wanting food they opened and closed their mouths, no sound, just waiting for their food. Just like home. The fish were good size, not surprising. I'm sure the other guests enjoyed feeding them as much as we did.
I might have to give some thought to caring for fish now
