Advice on building a community
If you will use this list to plan out your own saltwater aquarium community, here is some advice to consider.
Damselfish and Clownfish
Between the 7 Damselfish and Clownfish options listed here, you should pick only 1 species. If you decide to go with the damselfish species, you should get either 1 individual, or a small shoal of 5-7, if the tank is large enough. You can get 2 of the same species for clownfish, and they should pair up and may even spawn in your tank.
You should also be able to make a shoal of PJ cardinals if you want, and you can mix Banggai cardinals and PJ Cardinals, but Banggai’s are aggressive with each other, so it is probably best to have a big shoal of 7, a bonded pair or a lone ranger.
Just pick one, and add them to the tank after your other fish have had some time to establish their territories in the tank first. You don’t want to mix dottyback species and even use caution to keep two of the same species. They may pair up or tear each other apart.
