I don't think there's a way around anemone. I'd rather not get an anemone if I am not willing to shell out money. Some may tell you that yes you can get anemones with PC
lighting of about 6500K/10000K Daylights and actinics powering 5W per gallon. But if you make short cuts, you'll get cut short.
In my honest opinion, a clown doesn't have to host an anemone per se. I've seen clowns hosting leather corals or bubble corals, plate corals, even some types of mushroom corals. Those corals are the rather easy-to-moderate difficulty level. You do need prestine water parameters, good calcium, and a good PC
Check this out. I am preparing this 55G 4-ft tank for corals. I am chasing numbers right now but am getting there really really closely.
Calcium @ 370, Nitrates at 10, kH
at 350, pH at 8.1, and lighting at 260 watts. I am not expecting anemone or soft polyp stonys here. But I am looking at bubble coral, mushrooms, polyps, and a plate. I may even be lucky with pulsating xenia. But I don't want to play with that specific coral just yet.
