Let's start a thread on R2R for those who are trying to successfully keep a group of clownfish in a tank.
Historically, a pair of clownfish per tank has been the best way to successfully keep clownfish, especially more aggressive types like Maroons. However, there have been occurrences where reefkeepers successfully put together "harem" tanks, or circuses.
Famous tanks:
Bulk Reef Supply 120 Gallon

Mobert (Mona)'s tank
