So my tanks been running a little over a months now and my first fish purchase was a pair of clowns (of course!). They're a little smaller than an inch and follow each other everywhere. One has done the little ceasing thing to the other but the other never attacked it. Im not sure if they're paired/pairing. If they get separated one will swim frantically until he? finds her? Lol. Anyways my question is they sleep together side by side every night in the same corner of the tank, when would it be appropriate to get an anemone? I don't want to kill it by getting it too soon but they seem like they need a nice place to settle down!
