Most I've had in my 14 was 4, but is was not for long. How long has your tank been set up? If you posted I missed it. Any coral or fish is going to like an established tank, some coral and most anemones need at least 6 months. Some clowns need a lot of room even though my mom had two gold stripe maroons in her 14, not recommended. I personally keep it at 3 in my 14 but my tank has been set up for almost a year now. Really you're going to need to add fish one at a time and 2 weeks apart for good measure. Another trick I learned, after getting yelled at on here, was to do a lot of research on the fish first. Most online stores give a good description of their needs and tank size. Just for the sake of asking questions tell us how much live rock you have and what kind of clean up crew and if the tank has been modded in any way. I'm surprised no one has asked for these yet.
