After work today, I headed out Roswell Road, about a mile past the Perimeter, to a tropical fish store. I was hunting a specific fertilizer for the plants in my aquarium and I did find that, but as long as I was there, I browsed the shop, and turned up a bunch of these guys:
They are known in the trade as Corydoras julii, though they are almost certainly actually Corydoras trilineatus. Hmph. Anyhow, they are delightful little guys, now about an inch long, and I picked up three of them. They have this charming habit of swimming around in schools, with their noses in the gravel, looking for some left-overs for lunch. Very cool.
