Stocking question

[Ranchhand02]

I have a jbj nano cube 28 gallon and I currently have four small clownfish in the tank. I also have several lps and zoa frags in the tank. Do you think four fish is all I should put in the tank or could I add one more clown down the road if I wanted to?

You are almost certainly going to have major battles as the clowns you now have in your tank mature, so no, adding one or two more is not a good idea. A mature mated pair of clowns will claim about a 30 gallon chunk space, so with only 28 gallons things are going to get ugly. You may be okay for a few months or even a year or two, but eventually things are not going to go well.
