When betta fish go to sleep what do they look like?

Betta fish don't have eyelids, so they don't close their eyes when they sleep. However, there are some signs that indicate they are resting:

* Reduced movement: They will become less active, staying still at the bottom or near the surface of the tank.

* Fins held close: Their fins will be held close to their body, rather than being spread out.

* Dullness: Their colors may appear less vibrant and their eyes might look cloudy.

* Breathing slower: Their breathing rate will slow down significantly.

It's important to note that these signs are not always obvious, and some bettas may appear to be sleeping even when they are not. If you are unsure whether your betta is sleeping, it's best to observe it for a while and see if it exhibits any of the signs listed above.

Here's a fun fact: Betta fish are known to "sleep" with their heads down, often resting near the bottom of the tank.
