Striped Dottyback
Sankey's dottyback stands out in its family: FishBase and retailers both describe it living in loose colonies on wild reefs, and it is one of the very few dottybacks that tolerates its own kind in captivity — small groups introduced together at the same time can settle without the usual infighting. At around 7 cm and widely captive-bred, it's an easy, hardy reef fish, but it is still a carnivorous micro-predator that will opportunistically pick off a small ornamental shrimp or hermit crab given the chance. Best introduced as a same-size group all at once rather than added one at a time.
