To figure out what kind of fish you have, you'll need to provide me with some information. Tell me about:
* Appearance: Describe the fish's size, shape, color, markings, fins, and any other distinguishing features.
* Location: Where did you get the fish? Was it caught in the wild, purchased from a pet store, or given as a gift? Knowing the location can help narrow down possibilities.
* Behavior: How does the fish behave? Is it active, shy, aggressive, or peaceful?
* Habitat: What kind of water conditions does the fish live in? Is it a freshwater or saltwater fish?
Once you provide this information, I can help you identify the species.
You can also try using online resources like fish identification websites or apps, or consulting with a local fish expert.
