Hey Tim. I'm not all to sure that another Anem. will solve your problem. Clowns pair off and if they've been together and "alone" as in not around any other clowns for any decent length of time , then you have a male and a female.. and the female will without a doubt pick on the new one until it's to stressed to survive. Unless you have a very large tank I would recomend removing the new guy.. He could survive for a while but it would only be a short term thing. There is a great forumn on RC about clowns and Anems and a fantastic book written by Joyce D. Wilkerson "Clownfishes" that would serve as a good guide on Clowns. They are protandrous hermaphrodites. Meaning that They are all born as males and eventually the more agressive bigger fish will then morph into a sexual female and the second will be her sexual male. In the wild they live in small groups and will accept a juvenile male until the Sexual female passes and then they each take one step up, so to speak. In aquariums however they usually will bully until stressing the smaller clown to death, so they are best kept in pairs, unless all 3 introduced together at the same age or in the very largest of aquariums and even then usually the loss of the youngest is normal. There are exceptions , but this is generally the rule .. I'm sure you will find some others who have had some experience and say otherwise, but not many. If you do insist on keeping them together there are some ways to introduce a new clown. I once had a pair of Maroons and the male passed. I had to introduce a new male but everytime I did the female tore him to shreds. Eventually I had to conceal him in a clear plastic container with holes for flow. This gets both fish used to the scent and sight and limits aggression over a longer period of time... Best of luck ...
