I am new here also so dont take my advise over these folks, they are verry novice and profesional with much documneted information.
I have a 30 gallon tank salt water , I have 2 HOB filters that I have removed the filter media , I use them as small sumps,,,I have a airstone in each one that I can controll seperatly,, they also provide curent flow,I have 1 fluval canister filter that I use however I have removed the bio filter from it and only use the canister for charcoal and amonia control media,,,it also provides for water curent,,,, I would sugest that you start off slowly , dont rush this , you wont like the results.
I have allways used a couple of damsels to start the tank off.
They are verry hardy .
I would only sugest,,,, that you establish a colture of micro inhabitants ,, copepods , copepeds a asortment of snails when you start to see a little algae ,,,life in your rock dont start to bloom IMO untill after it has cured out, if you buy rock from a LFS it may or may not contain these necessary criters, and i tmay or may not be cured.
Test kits , are a must.
Thermometer a must.
It wouldnt hurt to have a extra tank around or at the least a 5 gallon water jug with the top cut off in case you need it.
They come in handy.
I would think the fish you described would be small enough to do well IF you maintain the water quality and temps they need and furnish them with a habitat that is close to their natural one..
There are quite a few who get into this hoby that dont last long because they did not do their homework and study the chosen inhabitants and their needs.
It can be verry heart breaking to buy a 35 dollar fish and wake up the next morning to see its tail sticking out of the mouth of a 5 dollar fish.
IMO you should also decide if you want to do a tank with corals and fish, a predator tank or just what ya want to do with it,,,I am definatly no expert on compatability however I did see a link on the forum that will guide you .
I always preferd a non predatorial tank .
Others like to see things eat other things.
Its all what ya like.
Keep in mind also one small but important thing and that is the availability of the parts for your equipment should something break down on you , it never hurts to have some sort of back up equipment regardless of size ,a few spare parts or even a extra air pump that runs on bateries,,,it may save the life of you new friends should something happen.
A good time to buy these items are while you are leting the tank cycle and you are board!!!!
Best wishes in your new hoby and I hope you can find the enjoyment that many others have .
I hope my coments are a worthy adition to what the folks on here have to offer.
I also would just sugest if you add a copeped or copepod couture to your set up after it is established to do it when the predators are not as active, I add my when the lights are off, it seems to give them a fighting chance to get to the rocks before they are eaten.
Cheers
