A closeup of the fishtank. Proteus is in the compartment on the left; Eris is in the rightmost compartment. The middle one is empty right now.
It took Eris a while to get used to not being in one of those tiny little bowls, but he's finally gotten used to swimming upward. Proteus, on the other hand, sticks to the bottom, near the glass beads.
