Starting your new aquarium hobby can be as easy as A-B-C if you’re following the proper guidelines in proper fish keeping. A fish tank is considered to be a “nano tank” when it could hold 30 gallons of saltwater or less. Though an aquarium within this size looks stress-free to maintain, but there’s more to it than meets the eye.
Experts agree that bigger tanks are easier to maintain for beginners due to the fact that the higher volume of water provides a buffer to any sensitivities in water quality and temperature. However, it isn’t THAT much more difficult if you’re following the proper guidelines in fishkeeping.
One thing that you should consider when you start your new nano reef tank is the choice of small saltwater fishes that could be best suitable for your tank. Keep in mind that the fish species should not be aggressive and the choice of fish you choose to stock is compatible with each other.
To help you get started, here is a list of 10 best nano saltwater fish for your nano reef tank:
