Bold black-and-white striped fish — one of the most recognizable damsels from Finding Nemo. Extremely hardy and cheap, making them popular as tank cycling fish. However, they are notoriously aggressive and territorial, harassing and killing more peaceful fish as they mature. Think carefully before adding one permanently — many reefers regret it.

Extremely cheap and nearly indestructible. Great for cycling but may cause problems with peaceful tankmates long-term.
