I wanted to buy 2 Longfin Mocha clownfish and 2 Phantom Clownfish from cultivatedreef.com. I would order them at the same time so they would hopefully be delivered at the same time. I am worried about adding all of them in the same tank since i know that some clownfish will fight and end up killing others. I don’t want to spend $300 on the longfin clowns just to have them die in a week or whatever. So my question is, if I add all four of them, two pairs at the same time, would that lessen the chance of them fighting? Are Phantom clownfish or the long finned more aggressive? Do you think this would be okay to do if I add them into one tank at the same time?
