No, not fish for eating, fish for looking at.
Today, a good friend of mine came over, and while he was here, he looked at my fish tank and declared that it's now looking quite healthy. He's good with fish tanks, so I regard him as a bit of an expert. That's why if he says the tank is in good shape I believe him.
I'd promised myself to get some nice new fish as soon as things seemed to be going well, so today was fish buying day!

We spent some time looking at all the pretty fish, and contemplating how suitable they'd be for our tank, regarding the fact that it's got a crayfish as well. Obviously, we were looking for some fast swimmers, and preferably for inhabitants of the top half of the tank, since crayfish can't go there.
One of the salespeople came over to help us and started to talk fish with us. This lady clearly knew her fish, and her crayfish too.

We ended up getting some gourami fish: I already had a lone three spot gourami lady, widowed a few months ago, and blind on one side, which makes her swim in a peculiar slanted way. But she still manages to avoid the crayfish quite well, so she deserved some sympathetic company. We got her a female friend of the same species, and a male and female of the 'gold' variety. The color variety doesn't seem to bother the fish, they make friends just the same, so the male now effectively has a harem of three ladies, which is said to be a good ratio. (I'm glad I'm not a gourami!)
In fact, it reminds me a bit of a BookCrossing meeting.
The new gouramis are much smaller than the older one, which made them much cheaper, and they'll grow soon enough.
