Just take a little more patience, sort of like having a house full of orchids instead of rubber plants.

Get the necessary kit (not from this country)
UV lights
|Regular clean seawater supply - the corniche doesnt count!
Protein skimmer
Filters (big ones)
air pump and you r away.

I havent bought stuff from shops, just caught it myself and let go again after a few months, if it was not eaten by something else......

But i have packed it up now.
