What size of tank are you thinking? A smaller nano like a 5 gal. or a larger nano, closer to maybe 20 gallons? Either way you will want to make sure you are topping off daily with fresh water to make up for the evaporation, or your salinity levels will go up. You'll want to do 10 percent water changes weekly (with saltwater) and do some algae scraping, sand vacuuming, pump/powerhead cleaning, etc. Also, have you kept saltwater before? A lot of people will tell you that nano and pico tanks are difficult to keep, but I think it is probably just different. You have to do maintenance more, but it takes way less time to clean a 10 gallon than a 90 gallon. It's just a different set of responsibilities. You will want to do a lot of reading about saltwater everything. Fish, corals, lighting, equipment, etc. You will have to decide if you want to use a protein skimmer or not. I would just start with the size of tank you exactly want, because that is going to be a major factor in what you can put in the tank. Knowing what kind of animals you want will help you choose what size of tank you want. For example, you can't put a hippo tang in a 10 gallon nano reef. But you could put other things.

Keep us posted, and if you have any questions don't be afraid to ask.

like 20 for clownfish i love two banded clownfish so closer to 20 gallons and never did saltwater but ive done freshwater and ive had a albino ruby shark which wasnt easy and had it for a couple months if that counts for anything and i can deal with maintace i know how it works

Yeah. Those could get to 5 inches so for two you might even want to go bigger depending on what else you want. If you want two, and still want a smaller tank, you could get away with putting two ocellaris clowns. I've seen people that keep a pair of ocellaris clowns in a 12 gallon nano cube or 14 gallon bio cube. My 12 gal. nano cube dx is cycling right now and I am planning on putting: 1 ocellaris clown, 1 firefish, and 1 yellow watchman goby. Were you wanting to use an all in one kit like a nano cube or something or were you wanting to piece it all together? If you haven't already and want a smaller nano for a good price and quality, I would look at a 14 gallon bio cube or a 12 gallon nano cube dx. Make sure if you look at the nano cube you are looking at the dx, because with the regular one you can't keep like hardly any corals. In one of those two 2 ocellaris clowns would fit, but that would be all the fish you could put in there. If you are looking for something a little larger I'd look at the 24 gallon nano cube, the 29 gallon biocube, or the 28 gallon hqi nano cube. They are more expensive though, which is why I settled for the 12 gal. You can also get some pretty good deals on used ones, for example, the 12 gallon nano cube dx is usually about $175, but I got mine used for $60 with a bunch of extras. In one of those larger ones, you could probably put a pair of those two banded clowns and then maybe one or two more fish just depending on the type. Here's a link to a page with some good nano fish: Nano Fish

20g is an okay size for a pair of ocellaris, but I wouldn't put in any more fish if that's the route you go. Did you want to put the tank together yourself or get a full setup (nanocube or biocube)? Also, what kinds of corals do you want to keep? This will make a difference with the kind of lighting you'll need. Keep in mind that with a nanoreef, you'll be doing regular water changes; I do a 25% WQ once a week in my 24g. You don't really need a protein skimmer IMO if you're doing regular water changes and not over feeding the tank.
