i got a saltwater tank as my first aquarium few years ago

not that hard
just watch the salinity
bigger the aquarium, the better.
pulsing xenia are fascinating corals that wont die.

i cycled my tank with hermit crabs and a good sandbed
dont forget to do lots of research, its the fun part of the hobby (;
welcome to the hobby and have fun (:
