I bought an established reef tank from someone and have recently set it up in my home. The tank also included coral and other livestock. Included was a large green carpet anemone. The owner tells me that it will not bother my fish or corals and he never had a problem with it. I, of course, I have my doubts. If I moved the carpet anatomy to a 35 gallon tank, I could keep it with clown fish as a Sort of nano tank. Having had no experiences with carpet anemones, my question is whether the 35 gallon tank is sufficient. I hear carpets are difficult to keep...exactly why is that? Because they are predatory or because they need steady parameters. My 35 gallon tank is basically a quarantine tank with a Seachem Tidal 55 hang on the back filter. No skimmer. No other filtration. I would like to put the carpet in there permanently. Any advice? What lighting would be necessary. And relatively inexpensive!?
