Hey!
I'm brand new to the saltwater aquarium hobby, I've been keeping freshwater tanks since as far as I can remember. My dad always had fish tanks even from before I was born! I got more interested in fish keeping after discovering aquascape and nature style aquariums. I've been doing that for the past 10 or so years but only recently hit my stride on it. That being said I started keeping more advanced aquascapes and livestock that required RO water and figured RODI was only a short push away and if I'm making freshwater I might as well give saltwater a go! I'm also a scuba diving instructor so the fish/plant/coral obsession runs pretty deep for me!

I retrofitted an old UNS System to saltwater and holy moly. This is much more addictive then freshwater, a totally different vibe and style of keeping. I'm completely obsessed! I've got a 20g Cube, with primarily zoa, paly and mushrooms at the moment. Recently added a super cheap torch and hammer to see how they do. Running for about 6 months.

Let me know your thoughts! I have a clean up crew but no fish or showcase livestock yet, would love some suggestions for a light bioload! I was thinking a group of sexy shrimp and possibly a pistol goby pair. On the freshwater side I am very shrimp dominant so, very happy with shrimp only but would be delighted to try some nano fish here.

Attached is a picture of the tank right after the lights turned on. I'm still figuring out the best ways to photograph this so please forgive the poor quality.
Here are a few closeups of some of the starter corals I've got going

Im not to familiar with fresh water shrimp... but welcome to saltwater shrimp! I freakin love sexys! They are known to posibly pick on coral.. so thats an issue.. so research and plan accordingly.. but also you have skunk cleaners and fire shrimp that are mainstays and awesome! Peppermint shrimp that are nice looking and are known to possibly help with aptasia (pest nems)... and the absolute tank of shrimp! Suit of armor wearing, destroyer of star fish! The harliquuuuiiiiin shrimp! My favorite! Ill be honest here though. It literally only eats star fish so you cant keep any stars. Unless they are for feeding the shrimp. But! Watching a 1" shrimp peal a chocolate star off the glass and take it apart one leg at a time while keeping it alive.. epic!

Also lets not forget the super cool crabs, and snails you can get! Bro.. salt water is wild! Hope you have good luck and enjoy the journey!

Welcome! Great set up to get you going!

Also at 20 gallons if your looking for some fish you are size limited.. most sites can steer you to nano fish but clowns are classic but can be agressive along with damsels.. watchman goby/ pistol shrimp pairs are an absolute must in any tank but especially small tanks! I like my royal gramma and purple fire fish who are both very mellow and pretty..
 
Welcome, glad you are here! Might I suggest a rock flower anemone to host your sexy shrimp, easy nem and come in beautiful colors. I know others might disagree but I wouldn’t have a reef tank without a clown fish pair. Since you like shrimp how about a pistol shrimp and goby pair. Such a cool relationship between the two.
