Thanks bro iskay for all the links. Yes, I've read up on the nitrogen cycle and also the cycling with prawns to expedite the bacteria build-up.
As for the clowns and anemones, I probably may not get an anemone now that so many bros have advised against it and am toying (and will be reading) on the torch and hammer corals suggested. However, due to no chiller, I'll first have to establish if a fan will suffice since the initial thought was for FOWLR and not to cater to corals which I know requires A LOT more work in terms of nutrient supply, cold water, sufficient lighting, etc.
I would however still want to try create the scene for clowns "frolicking" (with anemones, hammer / torch corals, what else?).
