Hi, and another welcome from me.
I read through the thread...there is a SOFT cycle you can do to help the fish. You have to have made up 24 hours in advance saltwater on hand, and as soon as you notice an ammonia spike do a 30% water change. This will keep the fish alive. It will streach out the cycle time but keep the fish safe.
Now for some good advice.
Do not get a small blue tang and plan to move it later...they are able to go flat and hide down to the last rock to get them out. That may not sound so hard, but remember a few years from now that will mean to compleatly break down the rock work and possibly stir up toxins deep in the sand...and could kill all the other fish in the tank. So get fish that are the right size for your tank to sustain them for their life span.
Next...you do need more rock, like halfway up the tank amount of rock.
And last but not least. ONLY one pair of clowns per tank. SW fish are very territorial, and kill fish with the same body type or color. Keeping this in mind will save you a lot of money. Frankly my clown fish is the least liked in my tank...and if my mother didn't like them I wouldn't keep them at all. The only thing they do is hug the corner and don't swim around like other fish except at feeding time. They find something to hug and attach themselves to, like to input and output hoses on a canister filter...usually NOT the anemone you purchase for them.
Oh and speaking of anemones...they need a tank 6 months mature at least and a ton of bright lights...They eat fish or anything else stupid enough to get close to it. Should a clown actually go to it, they will protect the other critters by chasing them away from their buddy the anemone, but remember..clowns seldom do what you want them to. Also the anemone is able to detatch and move where they want. Like behind rocks, or in another inconenient spot. Add to that you have to cover all power heads or they commit sushi by getting sucked up into it. Also a covered Power head means it clogs fast and every week to every other day you will have to clean the material you cover the PH with. anemone = PAIN in the butt.
A fantastic companion to take to the fish store with you....
