When I work at a zoo or Aquarium I definitely enrich the fish. It can be different food types, a bubbler, rearranging their tank, adding new things to the tank, changing up the lighting, freezing their food in ice cubes or putting it in puzzles. I have some pictures of fish enrichment somewhere near the beginning of my blog. I have no idea what I tagged it as three years ago. And you probably don’t want to scroll till you’re 90. 😂 But, remember, just doing general tank maintenance counts as enrichment in fish world. Water changes, taking things out to clean them, small changes in water chemistry, putting your hand in there, turning the flow to the tank off, are all very enriching.
For more intelligent fish like cichlids and bettas, putting an interesting object just outside the tank can also provide some level of enrichment. They also like TV! I’m not sure what they can see of it, but they’ll definitely watch the motions. Show your fish Youtube videos.
