A few weeks ago I was given a humu triggerfish and he was very active and swam all over the tank. No he seems to swim for an hour our two, then he goes and lays under a rock in the bottom for some time, then eventually he makes it back to swiming. I was wondering if this is normal. All the water parameters are good and he is still eating well. He just seems like he takes "naps" throughout the day. Any opnions are welcome.
