I hadnt planned on cycling with a live fish. As far as maintenence, Likely water change every two weeks, with changing filter media etc when the water is low. This will be my first foray into corals, so I'm going to go very slow on that front.
Take em back for the lfs for them to hold him for the time being, a good lfs would understand. Did you use live sand and live rock? If you did It would be much better as you would only have a mini cycle probably lasting just a few days instead of a longer cycle lasting upwards of a month or more.
What kindve filter media do you have? I see it's a drawer type of deal, seems like a neat lil setup. I would suggest cleaning/changing/rinsing them out once a week. Any longer then that and they will likely become nitrate factories from the trapped detritus being broken down at a fast rate.
For a maintenance routine I highly suggest blowing off your rocks with a turkey Baster or powerhead once a week, let the water clear (about an hourish) then move as much sand out from underneath stuff as you can to make it easily accessible then vacuum the sand. This is where your water change comes into play. Vacuum the sand with a gravel vac into a 5g bucket, do as much or as little as you want but the more you do, the more waste material you can get out. Takes a little practice but you should be able to do your whole sandbed in 5gallons or roughly 10% of your water volume. The more waste material you can keep out the less you will have to worry about inorganic nutrients.
Or you can wait and clean once every two weeks, once a month, bi-monthly, ect.. But then you will have to worry more about inorganic nutrients and thus supplement with carbon, gfo, and all that jazz. All of which will still need reactors cleaned, chemicals replaced, more testing to see if and when the chemicals are getting exhausted, so fourth and so on.
Really up to you on how you wanna do it, but I find the first suggestion easier on myself, my tank and my wallet.
