Note: There is a lot of controversy around the idea of keeping saltwater fish in tanks under 10g. Whether or not it is ethical will be up to you to decide and not something I'm going to get into. Like it or not, the fact is there are going to be people who do it. Therefore, I would rather at least provide those people with some guidance to make good choices instead of just leaving them in the dark.
Note Mandarins/Dragonets: There is a lot of controversy around the idea of keeping fish from the Dragonet family in nano tanks. Whether or not it is ethical will be for you to decide and not something I'm going to get into. I personally do not encourage people to keep dragonets in nano tanks, however, despite my feelings there a many who have successfully kept them in smaller tanks, there for I will include them in this guide.
