Happy Fishes

These are long overdue, but here are a few pictures of the sticklebacks enjoying their home in the lab.

Side-by-side nest comparison. The left side shows a nest. A male buries bits of plants in the sand and then the male creates a tunnel through the nest. The right side shows the same nest outlined with arrows showing the entrance and exit holes.

Curious fish come to check out the camera. Fish are housed with the same species and sex until they are ready to use in the experiment.
