@Great Argus yeah, it was quite unusual for a sunfish exhibit, there were also some bigfin reef squid hanging out towards the top (and even eggs, you can see them on the left side of the rockwork at the bottom), and supposedly a giant pacific octopus (i saw a pic posted here of one in this tank, no sign of it when i was there). i can't help but think that the tank was far too small for the sunfish (they could only swim about 4-5 times their own length before turning), it was more vertical than horizontal, and they kept bumping into the sides. they had a lot of lesions and worn away patches of skin (the white patches on the face and fins), presumably from rubbing against/bumping into the glass. it was kind of sad.
