Hello saltwater people
. I am completely new to salt water and no absolutely nothing about anything, but i had been pretty succesful with my fresh water aquariums and i remember someone telling me that if i can succesfully keep my discus fish then i can succesfully keep a saltwater aquarium, i don't know if this is true or not but im willing to find out
. If i already have the the 20 Gal. aquarium but nothing to help my saltwater needs what would i need to set up a nice small salt water aquarium?, and what are some nice small saltwater fish to put inside of it. Anything to help this noob (me) is appreciated thanks
