Can a fish be depressed? This question has been floating around my head ever since I saw a sad-looking Siamese fighting fish in a hotel. His name was Bruce Lee, according to a sign beneath his little bowl.

On the bottom of the little bowl was Bruce Lee, totally still, his lower fin (鳍) somewhat injured. When he did finally move, just slightly, I got the sense that he would prefer to be dead.

The pleasant woman at the front desk convinced me that he was well taken care of. Was I simply incorrectly supposing his lethargy was a sign of mental suffering?

Later on, I sought answers from scientists. It turns out that not only can our gilled (有鳃的) friends become depressed, but some scientists consider fish to be a promising animal model for developing anti-depressants. New research has been completely changing the way scientists think about fish, building a case that pet and owner are not nearly as different as many suppose.

Dr. Pittman likes working with fish, in part, because they are so obvious about their depression. He can reliably test the effectiveness of anti-depressants with something called the "novel tank test". A zebra fish gets dropped in a new tank. If after five minutes it is hanging out in the lower half, it's depressed. If it's swimming up top — its usual behavior when exploring a new environment — then it's not. The seriousness of the depression, he says, can be measured by quantity of time at the top vs. the bottom, all of which seemed to confirm my guess about Bruce Lee.

"One of the things we're finding is that fish are naturally curious and seek novel things out," said Dr. Braithwaite.

In other words, your goldfish is probably bored. To help prevent them from depression, she suggests introducing new objects to the tank (缸) or changing the location of items.

Dr. Brown agrees, pointing to an experiment he conducted, which showed that if you leave a fish in an enriched, physically complex environment — meaning a lot of plants to bite at and cages to swim through — it decreases stress and increases brain growth.

The last time a guest posted Bruce Lee to Instagram he was looking good and lively. Perhaps that new green leaf in his bowl had provided the enrichment he desired.
