So the previous post (below), which discusses the specimen container that I modified to house some fry, didn't include any actual photos of the fry.
To remedy that, here are a couple of shots of the container in use. The blue "floor" of the container is a cut-to-fit sponge. Because the container is transparent and resides at the top of the aquarium just under the canopy, all perceived predators can been viewed through the bottom of the container. Fry are instinctually averse to predation, so in order to lessen their anxiety by seeing predators below them and to encourage them to exit their shells, I used the sponge.
The fry are Telmatochromis sp. "temporalis shell" and, as the name suggests, they are fond of shells in their native habitat. The two shells in the container aren't native to Lake Tanganyika, but the fry don't know that nor do they care.
