Usually, I see spotted pufferfish swimming alone, but these three spent some time together as a group. Also unusual was that they were swimming up in the water where they caught the sunlight.

They look rather more like toys than actual fish somehow!

They’re quite cute. I’ve never seen one puffed up, when they look almost circular, but for that to happen they have to feel very threatened.
